20. Precautionary Notes in Using the Device

20.3.5 Timer Z

1. When count is stopped by writing "0" to the timer Z count start flag, the timer reloads the value of

reload register and stops. Therefore, the timer count value should be read out before the timer

stops.

2. When count is stopped by writing "0" to the timer Z count start flag (all modes) or by writing "0" to

the one-shot start bit (programmable one-shot generation mode/programmable wait one-shot gen-

eration mode), the timer Z interrupt request flag becomes "1" and an interrupt occurs. Thus, disable

interrupts before the timer stops. Furthermore, set the Timer Z interrupt request bit to "0" before

starting counting again.

20.3.6 Timer C

1. Read out the timer C or timer measurement register using in word-size.

Even if the Timer C is read out in word-size, the timer value is not updated during the period the

high-byte and low-byte are being read.

Example:

MOV.W

0091H,R0
