R/W Description
R/(W) Reserved
The initial value should not be changed.
R/W PWM Enable
Starts or stops the PWM D/A counter (DACNT).
0: DACNT operates as a 14-bit up-counter
1: DACNT halts at H'0003
R Reserved
These bits are always read as 1 and cannot be
modified.
R/W Output Enable B
Enables or disables output on PWM (D/A) channel B.
0: PWM (D/A) channel B output (at the PWX1 pin) is
disabled
1: PWM (D/A) channel B output (at the PWX1 pin) is
enabled
R/W Output Enable A
Enables or disables output on PWM (D/A) channel A.
0: PWM (D/A) channel A output (at the PWX0 pin) is
disabled
1: PWM (D/A) channel A output (at the PWX0 pin) is
enabled
R/W Output Select
Selects the phase of the PWM (D/A) output.
0: Direct PWM (D/A) output
1: Inverted PWM (D/A) output
R/W Clock Select
Selects the PWM (D/A) resolution. If the system clock
(φ) frequency is 10 MHz, resolutions of 100 ns, 200 ns,
6,400 ns, and 12,800 ns can be selected.
