Description
Test Mode
Selects test mode, which is used in testing this LSI. Normally
this bit should be cleared to 0.
0: PWM (D/A) in user state: Normal operation
1: PWM (D/A) in test state: Correct conversion results
unobtainable
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
Reserved
These bits are always read as 1 and cannot be modified.
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
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
Output Select
Selects the phase of the PWM (D/A) output.
0: Direct PWM (D/A) output
1: Inverted PWM (D/A) output
Clock Select
Selects the PWM (D/A) resolution. If the system clock ( )
frequency is 10 MHz, resolutions of 100 ns and 200 ns, can be
selected.
0: Operates at resolution (T) = system clock cycle time (t
1: Operates at resolution (T) = system clock cycle time (t
