TCO Timer reload value (TCO_TRLD_VAL) (tco_trld_val):
Value that is loaded into
the timer each time the TCO_RLD register is written. Values of 0000h or 0001h will be
ignored and should not be attempted. The timer is clocked at approximately 0.6
seconds, and thus allows timeouts ranging from 1.2 second to 613.8 seconds. Note: The
timer has an error of +/- 1 tick (0.6s). The TCO Timer will only count down in the S0
state.
