R/W Description
R/W` Reserved
The initial value should not be changed.
R/W PWMX 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
R Always read as 1 and cannot be modified.
R/W Output Enable B
Enables or disables output on PWMX (D/A) channel B.
0: PWMX (D/A) channel B output (at the PWX1 output
pin) is disabled
1: PWMX (D/A) channel B output (at the PWX1 output
pin) is enabled
R/W Output Enable A
Enables or disables output on PWMX (D/A) channel A.
0: PWMX (D/A) channel A output (at the PWX0 output
pin) is disabled
1: PWMX (D/A) channel A output (at the PWX0 output
pin) is enabled
R/W Output Select
Selects the phase of the PWMX (D/A) output.
0: Direct PWMX (D/A) output
1: Inverted PWMX (D/A) output
R/W Clock Select
Selects the PWMX (D/A) resolution. Eight kinds of
resolution can be selected.
0: Operates at resolution (T) = system clock cycle time
(t )
cyc
1: Operates at resolution (T) = system clock cycle time
