Function
This the output from the chip temperature sensor.
NOTE: when reading these bits the SIF interface must be exteremly
slow, 1MHz range.
These are the values of the blown fuses and are used to determine the
available functionality in the chip.
(*** NOTE ***) These bits are READ_ONLY and allow the user to check
what features have been disabled in the device.
bit5 = 1: Forces Full Word interface
bit4 = 0: reserved
bit3 = 0: reserved
bit2 = 1: Forces Single DAC Mode. Note: This does not force the
channel B in sleep mode. In order to do so, user needs to program
the sleepb SPI bit (config10, bit 5) to "1".
bit1:0 : Forces a different bits size.

alarms_ mask
Function
Each bit is used to mask an alarm. Assertion masks the alarm: bit15 =
alarm_mask_zerochka
bit14 = alarm_mask_zerochkb
bit13 = alarm_mask_fifoa_collision
bit12 = alarm_mask_fifoa_1away
bit11 = alarm_mask_fifoa_2away
bit10 = alarm_mask_fifob_collision
bit9 = alarm_mask_fifob_1away
bit8 = alarm_mask_fifob_2away
bit7 = alarm_mask_dacclk_gone
bit6 = alarm_mask_dataclk_gone
bit5 = Masks the signal which turns off the DAC output when a clock or
collision occurs. This bit has no effect on the PAD_ALARM output.
bit4 = alarm_mask_iotesta
bit3 = alarm_mask_iotestb
