Description

DAC Control Register 1

Fields

DACBFEN

DAC Buffer Enable

0 (0): Buffer read pointer is disabled. The converted data is always the first word of the buffer.

1 (1): Buffer read pointer is enabled. The converted data is the word that the read pointer points to. It means converted data can be from any word of the buffer.

1 (01): Swing mode

2 (10): One-Time Scan mode

3 (11): FIFO mode

DACBFWM

DAC Buffer Watermark Select

0 (00): In normal mode, 1 word . In FIFO mode, 2 or less than 2 data remaining in FIFO will set watermark status bit.

1 (01): In normal mode, 2 words . In FIFO mode, Max/4 or less than Max/4 data remaining in FIFO will set watermark status bit.

2 (10): In normal mode, 3 words . In FIFO mode, Max/2 or less than Max/2 data remaining in FIFO will set watermark status bit.

3 (11): In normal mode, 4 words . In FIFO mode, Max-2 or less than Max-2 data remaining in FIFO will set watermark status bit.
