8.   Register descriptions
8.1  Register overview
This section describes all the registers used in the SE98A. The registers are used for
latching the temperature reading, storing the low and high temperature limits, configuring,
the hysteresis threshold and the ADC, as well as reporting status. The device uses the
Pointer register to access these registers. Read registers, as the name implies, are used
for read only, and the write registers are for write only. Any attempt to read from a
write-only register will result in reading zeroes. Writing to a read-only register will have no
effect on the read even though the write command is acknowledged. The Pointer register
is an 8-bit register. All other registers are 16-bit.
 
A write to reserved registers my cause unexpected results which may result in requiring a
reset by removing and re-applying its power.
