• Manufacturer Part Number: h8s-2635
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 Series
• Manufacturer: Renesas Electronics Corporation.

Note: The H8S/2635 Group is not equipped with a DTC.
19.1
The chip has an on-chip motor control PWM (pulse width modulator) with a maximum capability
of 16 pulse outputs.
19.1.1
Features of the motor control PWM are given below.
Maximum of 16 pulse outputs
Buffered duty registers
0% to 100% duty
Five operating clocks
High-speed access via internal 16-bit-bus
Two interrupt sources
Automatic transfer of register data
Module stop mode
Two 10-bit PWM channels, each with eight outputs.
Each channel is provided with a 10-bit counter (PWCNT) and cycle register (PWCYR).
Duty and output polarity can be set for each output.
Duty registers (PWDTR) are provided with buffer registers (PWBFR), with data
transferred automatically every cycle.
Channel 1 has four duty registers and four buffer registers.
Channel 2 has eight duty registers and four buffer registers.
A duty cycle of 0% to 100% can be set by means of a duty register setting.
There is a choice of five operating clocks ( , /2, /4, /8, /16).
High-speed access is possible via a 16-bit bus interface.
An interrupt can be requested independently for each channel by a cycle register compare
match.
Block transfer and one-word data transfer are possible by activating the data transfer
controller (DTC).
As the initial setting, PWM operation is halted. Register access is enabled by clearing
module stop mode.
