Description
FCTLL
DAC frequency control, 16 LSbs
FCTLH
DAC frequency control 4MSbs, PLL control
LEFT
DAC left channel PCM value
RIGHT
DAC right channel PCM value
Every fourth clock cycle, an internal 26-bit counter is added to by (DAC FCTLH & 15) × 65536 +
DAC FCTLL. Whenever this counter overflows, values from DAC LEFT and DAC RIGHT are read and
a DAC interrupt is generated.
