Bits 31:8 AWHT[23:0]: Analog watchdog high threshold
These bits are written by software to define the high threshold for the analog watchdog.
Note: In case channel transceivers monitor (AWFSEL=1), the higher 16 bits (AWHT[23:8]) define the
16-bit threshold as compared with the analog watchdog filter output (because data coming from
the analog watchdog filter are up to a 16-bit resolution). Bits AWHT[7:0] are not taken into
comparison in this case.
Bits 7:4 Reserved, must be kept at reset value.
Bits 3:0 BKAWH[3:0]: Break signal assignment to analog watchdog high threshold event
BKAWH[i] = 0: Break i signal is not assigned to an analog watchdog high threshold event
BKAWH[i] = 1: Break i signal is assigned to an analog watchdog high threshold event
