Register 83h: Sync Pulse Configuration REGISTER: ON/OFF
This register becomes read only when the Lock bit is set. Any further attempts to write to this register shall
have no effect.
Bit [4] of the Sync Pulse ON/OFF register controls whether the Synchronization Pulse is on or off (active
low). The default is ON.
Registers 86-88h: Smooth Temperature Reading Registers
The Smooth Temperature Reading registers reflect the smoothed temperatures of the internal and remote
diodes. Smoothed temperatures are represented as 8 bit, 2’s complement, signed numbers in Celsius, as
shown in Table 8.2 - Temperature vs. Register Reading. These registers are read only – a write to these
registers has no effect.
These registers hold appropriate values whether smoothing is enabled or not.
