17.1
The H8S/2646 Series has an on-chip motor control PWM (pulse width modulator) with a
maximum capability of 16 pulse outputs.
17.1.1
Features of the motor control PWM are given below.
Maximum of 16 pulse outputs
Buffered duty registers
0% to 100% duty
Five operating clocks
On-chip output driver
High-speed access via internal 16-bit-bus
Two interrupt sources
Automatic transfer of register data
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
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 (ø, ø/2, ø/4, ø/8, ø/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
automatically every cycle.
match.
Block transfer and one-word data transfer are possible by activating the data transfer
controller (DTC).
