9.1
The H8/2148 Group has an on-chip pulse width modulation (PWM) timer module with sixteen
outputs. Sixteen output waveforms are generated from a common time base, enabling PWM
output with a high carrier frequency to be produced using pulse division. The PWM timer module
has sixteen 8-bit PWM data registers (PWDRs), and an output pulse with a duty cycle of 0 to
100% can be obtained as specified by PWDR and the port data register (P1DR or P2DR).
9.1.1
The PWM timer module has the following features.
Operable at a maximum carrier frequency of 1.25 MHz using pulse division (at 20-MHz
operation)
Duty cycles from 0 to 100% with 1/256 resolution (100% duty realized by port output)
Direct or inverted PWM output, and PWM output enable/disable control
