BIT 7
SEE: Shadowed EEPROM Disable
0 = Enables EEPROM writes to the shadowed EEPROM bytes.
1 = Disables EEPROM writes to shadowed EPPROM bytes during configuration, so that the
configuration of the device is not delayed by the EEPROM cycle time. Once the values are known,
write this bit to a 0 and write the shadowed EEPROM locations again for data to be written to the
EEPROM.
BIT 6
AEN: Automatic Enable
0 = The temperature-calculated index value TINDEX is writable by the user and the automatic
updates of calculated indexes are disabled. This allows users to interactively test their modules by
controlling the indexing for the LUTs. The recalled values from the LUTs appear in the DAC VALUE
registers after the next completion of a temperature conversion.
1 = The internal temperature sensor determines the value of TINDEX.
BITS 5:1
SRAM: General-Purpose SRAM. These bits have no affect on device operation.
BIT 0
SOFTTXD: Soft Transmit Disable
0 = DACs operate normally.
1 = The DAC outputs are forced to the bit value of the POL bit, which is located in the DAC’s
associate DAC POR register.
For example, when SOFTTXD is set and POL = 1 in the DAC0 POR register, DAC0 is forced to full-
scale output, but if POL = 0, DAC0 is forced to a zero output. This applies to all four DACs.
