SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER

Wait Mode

When a WAIT instruction is executed, the BCLK stops and the microcomputer enters the wait mode. In this

mode, oscillation continues but the BCLK and watchdog timer stop. Writing â1â to the WAIT peripheral

function clock stop bit and executing a WAIT instruction stops the clock being supplied to the internal

peripheral functions, allowing power dissipation to be reduced. Table 1.9.3 shows the status of the ports in

wait mode.

Wait mode is cancelled by a hardware reset or an interrupt. If an interrupt is used to cancel wait mode, the

microcomputer restarts from the interrupt routine using as BCLK, the clock that had been selected when the

WAIT instruction was executed.

Single-chip mode

Retains status before wait mode

When fC selected Does not stop

When f8, f32 selected Does not stop when the WAIT peripheral function clock stop bit

is â0â.

When the WAIT peripheral function clock stop bit is â1â, the sta-

tus immediately prior to entering wait mode is retained.
