CHAPTER 8 PULSE WIDTH COUNT TIMER (PWC)
■ Program example 2 for interval timer function (one-shot timer mode)
●
Processing description
• Generates a single 1.5 ms interval timer interrupt (one-shot timer mode).
• The TO bit is initialized to "1" and inverted after the interval time.
• The following shows the RLBR register value that results in an interval time of approximately 3 ms for
a 5 MHz main clock oscillation frequency. The count clock is 32 t
inst
(t
inst
: Instruction cycle).
RLBR register value = 3 ms/(32 x 4/5 MHz) = 117.2 (075
H
)
