SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER

PULSE WIDTH MODULATION (PWM)
The M37515M4-XXXHP has a PWM function with an 8-bit resolu-
tion, based on a signal that is the clock input X
IN
or that clock
input divided by 2.
Data Setting
The PWM output pin also functions as port P4
4
. Set the PWM pe-
riod 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(X
IN
)
= 31.875
(n+1)

) = 8 MHz)

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.
