Timing Register (TIM1/2)
Tables 25
through
29
contain various Timing Register
information. The TIM register is composed of two subregisters:
1. TIM1—Controls the watchdog timing selection as well as
either the watchdog window or the watchdog timeout
option (
Figure 25
and
Figure 26
, respectively). TIM1 is
selected when bit D3 is 0 (
Table 25
). Watchdog timing
characteristics are described in
Table 26
.
2. TIM2—Selects an appropriate timing for sensing the
wake-up circuitry or cyclically supplying devices by
switching the HS on or off. TIM2 is selected when bit D3
is 1 (
Table 27
).
Figure 27
, page 44, describes HS
operation when cyclic sense is selected
.
Cyclic sense
timing characteristics are described in
Table 29
, page 44.
Both subregisters also report the CANL and TXD diagnostic.
