Description
Reserved
These bits are always read as 0. The write
value should always be 0.
Dial Pulse Start
Start bit of dial pulse. Dial number within the
DPNQ register is output to AFE_RLYCNT as
specified by PPS, MRCR and MPCR. After all
dial number is output, DPE interrupt is
generated to modify the DPST bit to 0. See
section 22.4.3, DAA Interface for more detail
about dial pulse output sequence. Take care
that AFE_RLYCNT must be "H" to enable dial
pulse generating circuit
