SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
7516 Group
PULSE WIDTH MODULATION (PWM)
The 7516 group has a PWM function with an 8-bit resolution,
based on a signal that is the clock input XIN or that clock input di-
vided by 2.
Data Setting
The PWM output pin also functions as port P44. Set the PWM
period by the PWM prescaler, and set the “H” term of output pulse
by the PWM register.
If the value in the PWM prescaler is n and the value in the PWM
register is m (where n = 0 to 255 and m = 0 to 255) :
PWM period = 255 (n+1) / f(XIN)
= 31.875 (n+1)
s
(when f(XIN) = 8 MHz,count source selection bit = “0”)
Output pulse “H” term = PWM period m / 255
= 0.125 (n+1) m
s
(when f(XIN) = 8 MHz,count source selection bit = “0”)

Fig. 41 Block diagram of PWM function
PWM Operation
When bit 0 (PWM enable bit) of the PWM control register is set to
“1”, operation starts by initializing the PWM output circuit, and
pulses are output starting at an “H”.
If the PWM register or PWM prescaler is updated during PWM
output, the pulses will change in the cycle after the one in which
the change was made.
