3.2.2
Timer counter output (IT3~IT0)
The timer counter is cleared to 0 at reset. It is incremented, from 0, each time the fundamental
clock is input. The timer counter output transfers the inverted value of the timer counter to the
accumulator or data memory using port P5 input instructions [IN %IP05, A] and [IN %IP05, @LR].
Thus, 1 is read at reset. (Decrement)
Figure 3.5 Timer counter configuration
3.2.3
Watchdog timer output
The watchdog timer output becomes active 216/fc (s) after the timer is reset.
If the timer is not reset again before timer reset, TC9028P and TC9028F regards this as a CPU
runaway and resets the CPU.
4. Low power consumption operation
TC9028P and TC9028F features a hold mode for low power consumption operation.
4.1
Hold mode
The hold function stops system operation and holds the internal states in effect immediately before
stopping.
The hold function is controlled by the port hold mode cancellation function and by the hold instruction
[HOLD]. The hold cancel function is valid with pins P00~P03, and with pins P10~P13, P20~P23
(HCAN pins) which are switched using and option to input mode during hold mode.
