    Gets the CCD type. This uses the measured resistance of the first RTD. E2V CCDs have a PT100 RTD; ITLs have either a PT1000 or PT500 RTD.
    
    Returns:
    
    The encoded CCD type (ITL or E2V)
    
    Throws:
    
    REBException - If the resistance cannot be read, or the type cannot be determined.
  - readTemperature
```
public double readTemperature(int chan)
                       throws REBException
```
    Reads an RTD temperature. There are three possible RTD types: PT1000: Used by ITL science and guiding CCDs PT500: Used by wavefront CCDs PT100: Used by the raft RTD and by E2V science and guiding CCDs
    
    Parameters:
    
    chan - The RTD channel number: 0 - 2 for CCDs; 3 for RTM RTD
    
    Returns:
    
    The temperature (C), or NaN if conversion failed
    
    Throws:
    
    REBException
  - readIntTemperature
```
public double readIntTemperature()
                          throws REBException
```
    Reads the internal temperature.
    
    Returns:
    
    The temperature (C), or NaN if conversion failed
    
    Throws:
    
    REBException
  - readIntVoltage
```
public double readIntVoltage()
                      throws REBException
```
    Reads the internal voltage.
    
    Returns:
    
    The voltage, or NaN if conversion failed
    
    Throws:
    
    REBException
  - reset
```
public void reset()
           throws REBException
```
    Resets the chip.
    
    Throws:
    
    REBException
  - readRegister
```
public int readRegister(int regnum)
                 throws REBException
```
    Reads a register.
    
    Parameters:
    
    regnum - The register to read
    
    Returns:
    
    The value read
    
    Throws:
    
    REBException
  - writeRegister
```
public void writeRegister(int regnum,
                          int value)
                   throws REBException
```
    Writes a register
    
    Parameters:
    
    regnum - The register to write
    
    value - The value to write
    
    Throws:
    
    REBException
  - waitReady
```
public boolean waitReady()
                  throws REBException
```
    Waits for the chip to become ready after a conversion
    
    Returns:
    
    Whether conversion was successful
    
    Throws:
    
    REBException
