Configures an alarm. This routine configures the temperature and voltage alarms. There are eight alarms available, corresponding to the eight available DIO bits. If an alarm is enabled, its associated DIO line will be configured as an output on power on and driven to its non-alarmed state. The alarm conditions are evaluated every measurement cycle.

Input options:

Bit	Description
[0-2]:	input channel (0-7)
3:	units: 0 = temperature, 1 = raw
[4-6]:	threshold type:
	000 - alarm when reading > value1
	001 - alarm when reading > value1, reset when reading < value2
	010 - alarm when reading < value1
	011 - alarm when reading < value1, reset when reading > value2
	100 - alarm when reading < value1 or > value2
	101 - not used
	110 - not used
	111 - not used
7:	not used, must be 0

Output options:

Bit	Description
0:	1 = enable alarm, 0 = disable alarm
1:	0 = active low alarm, 1 = active high alarm
[2-7]:	not used

Parameters:: alarm - The number (0 - 7) of the alarm to configure.; iOptns - Input options.; oOptns - Output options.; value1 - The first alarm condition value.; value2 - The second alarm condition value.

calibrate
```
public void calibrate(int type)
               throws org.lsst.ccs.drivers.commons.DriverException
```
Calibrates the ADC channels. This is used after reconfiguring the channel(s). This may take up to several seconds, and the completion may be determined by polling the status with getStatus(). Temperature readings will not be updated while the calibration is ongoing, but DIO operations may be performed. The device will not accept setItem() or memWrite() commands while calibration is being performed. Additionally, any calibrate() commands with type argument other than 255 (calibrate abort) will be ignored. After a calibration is aborted, getStatus() will indicate a calibration error until a new calibration is started. Once voltage calibration has been completed successfully, the calibration path location in the isolated microcontroller's EEPROM will be updatated to indicate which path was used for the most recent calibration.

Parameters:

type - The type of calibration to perform: 0 = temperature, 1 = voltage, 255 = abort.

Throws:

org.lsst.ccs.drivers.commons.DriverException

UnsupportedOperationException

getStatus
```
public int getStatus()
              throws org.lsst.ccs.drivers.commons.DriverException
```
Gets the calibration status

Returns:

Throws:

org.lsst.ccs.drivers.commons.DriverException

UnsupportedOperationException

getBurnout
```
public int getBurnout(int mask)
               throws org.lsst.ccs.drivers.commons.DriverException
```
Gets the burnout status and clears it under a mask. This routine returns the status of burnout detection for thermocouple channels. The return value is a bitmap indicating the burnout detection status for all 8 channels. Individual bits will be set if an open circuit has been detected on that channel. The bits will be cleared after the call using the mask parameter. If a bit is set, the corresponding bit in the status will be left at its current value.

Parameters:

mask - The mask of status bits to clear (0 = clear).

Returns:

The burnout status (before being cleared).

Throws:

org.lsst.ccs.drivers.commons.DriverException

               throws org.lsst.ccs.drivers.commons.DriverException
```
Writes firmware code. This routine writes to the program memory in the device, and is not accepted unless the device is in update mode. It will normally be used when downloading a new hex file, so it supports memory ranges that may be found in the hex file. The microcontroller that is being written to is selected with the prepareDownload() routine.
The address ranges are:
0x000000 - 0x0075FF: Microcontroller FLASH program memory
0x200000 - 0x200007: ID memory (serial number is stored here on main micro)
0x300000 - 0x30000F: CONFIG memory (processor configuration data)
0xF00000 - 0xF03FFF: EEPROM memory
FLASH program memory: The device must receive data in 64-byte segments that begin on a 64-byte boundary. The data is sent in messages containing 32 bytes. count must always equal 32.
Other memory: Any number of bytes up to the maximum (32) may be sent.

count - The number of bytes to write.

data - The data to be written.
