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
