Use bit 7 (SP) in the RMLD reg-
ister to toggle the noise filter
sampling frequency between
PWM6/PWM8 and PWM3/
PWM5.

Controlling the SLOW Mode
The MN102H series microcontrollers have two operating modes: NORMAL and
SLOW. (See section 3.1, "CPU Modes," on page 72.) In SLOW mode, f
= 2 MHz, which affects the frequencies of the PWM3 clock and noise filter
sampling (PWM6/PWM8). Use the SPSLW bit (bit 6) of the RMLD register to
change which clocks and noise filter sampling that you use.
