DTPL
DTMF power level—16-bit format is 0x0(H)(L)0 where H is the
(–)dBm level of the high-frequency DTMF tone, and L is the (–)dBm level of
the low-frequency DTMF tone. Note that twist may be specified here.
DTNT DTMF on time (ms units).
DTFT DTMF off time (ms units).
RGFH Ring frequency high—Maximum frequency ring to be considered a valid ring.
RGFH = 2400/(maximum ring frequency).

MOD1 This is a bit-mapped register.
PRDD Pre-dial delay-time after ATD command that modem waits to dial (ms units).
The Si2403 stays on-hook during this time.
FHT Flash Hook Time. Time corresponding with “!” or “&” dial modifier that the
Si2403 goes on-hook during a flash hook (ms units).
