Description

DAC control register.

Fields

INT_DMA_REQ

DMA request

0 (CLR): This bit is cleared on any write to the DACR register.

1 (SET): This bit is set by hardware when the timer times out.

DBLBUF_ENA

DMA double-buffering

0 (DISABLED): DACR double-buffering is disabled.

1 (ENABLED): When this bit and the CNT_ENA bit are both set, the double-buffering feature in the DACR register will be enabled. Writes to the DACR register are written to a pre-buffer and then transferred to the DACR on the next time-out of the counter.

CNT_ENA

DMA time-out

0 (DISABLED): Time-out counter operation is disabled.

1 (ENABLED): Time-out counter operation is enabled.

DMA_ENA

DMA enable

0 (DISABLED): DMA access is disabled.

1 (ENABLED): DMA Burst Request Input 15 is enabled for the DAC (see Table 136).

RESERVED

Reserved, user software should not write ones to reserved bits. The value read from a reserved bit is not defined.
