Bit 7—Test Mode (TEST): Selects test mode, which is used in testing the chip. Normally this bit

should be cleared to 0.

Bit 7

TEST

Description

PWM (D/A) in user state: normal operation

(Initial value)

PWM (D/A) in test state: correct conversion results unobtainable

Bit 6—PWM Enable (PWME): Starts or stops the PWM (D/A) counter (DACNT).

Bit 6

PWME

Description

DACNT operates as a 14-bit up-counter

(Initial value)

DACNT halts at H'0003

Bits 5 and 4—Reserved: These bits cannot be modified and are always read as 1.

Bit 3—Output Enable B (OEB): Enables or disables output on PWM (D/A) channel B.

Bit 3

OEB

Description

PWM (D/A) channel B output (at the PWX1 pin) is disabled

(Initial value)

PWM (D/A) channel B output (at the PWX1 pin) is enabled

Bit 2—Output Enable A (OEA): Enables or disables output on PWM (D/A) channel A.

Bit 2

OEA

Description

PWM (D/A) channel A output (at the PWX0 pin) is disabled

(Initial value)

PWM (D/A) channel A output (at the PWX0 pin) is enabled
