Section 15 Timer RC
Section 15 Timer RC
Timer RC is a 16-bit timer having output compare and input capture functions. Timer RC can
count external events and output pulses with a desired duty cycle using the compare match
function between the timer counter and four general registers. Thus, it can be applied to various
systems.
Note: Timer RC is not supported in H8S/20223 and H8S/20203 groups.
15.1 Features
⢠Selection of seven counter clock sources
Six internal clocks (Ï, Ï/2, Ï/4, Ï/8, Ï/32, and Ï40) and an external clock (for counting external
events)
⢠Capability to process up to four pulse outputs or four pulse inputs
⢠Four general registers
Can be used as output compare or input capture registers independently
Can be used as buffer registers for the output compare or input capture registers
⢠Timer inputs and outputs
 Timer mode
Output compare function (Selection of 0 output, 1 output, or toggle output)
Input capture function (Rising edge, falling edge, or both edges can be detected.)
Counter clearing function (Counter cycle can be set.)
 PWM mode
Generates up to three-phase PWM output.
 PWM2 mode
Generates pulses with a desired period and duty cycle.
⢠Any initial timer output value can be set
⢠Five interrupt sources
Four compare match/input capture interrupts and an overflow interrupt.
