Bit 2—Output Format Select (PWCRm2)*
This bit selects the format of the output from the PWMm output pin.
This bit is write-only. Reading it always returns 1.
Bit 2
PWCRm2 Description
0 Pulse-division PWM
1 Event counter PWM
Note: * Implemented on H8/38124 Group only.
Bits 1 and 0—Clock Select 1 and 0 (PWCRm1, PWCRm0)
Bits 1 and 0 select the clock supplied to the 10-bit PWM. These bits are write-only bits; they are
always read as 1.
Bit 1 Bit 0
PWCRm1 PWCRm0 Description
0 0
0 1
1 0
1 1
Note: * Period of PWM input clock.
The input clock is φ (tφ * = 1/φ)
The conversion period is 512/φ, with a minimum modulation
width of 1/2φ
The input clock is φ/2 (tφ * = 2/φ)
The conversion period is 1,024/φ, with a minimum
modulation width of 1/φ
The input clock is φ/4 (tφ * = 4/φ)
The conversion period is 2,048/φ, with a minimum
modulation width of 2/φ
The input clock is φ/8 (tφ * = 8/φ)
The conversion period is 4,096/φ, with a minimum
modulation width of 4/φ
