Description
Reserved
The initial value should not be changed.
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
Reserved
Always read as 1 and cannot be modified.
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)
1: PWMX (D/A) channel B output (at the PWX1 output pin)
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)
1: PWMX (D/A) channel A output (at the PWX0 output pin)
Output Select
Selects the phase of the PWMX (D/A) output.
0: Direct PWMX (D/A) output
1: Inverted PWMX (D/A) output
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
1: Operates at resolution (T) = system clock cycle time (t
