C8/C9h Write/Read Debounce Time Register
This command applies to all channels and does not depend on the state of the Channel Enable Register.

Enable E1 (Global parameter)
EE1 = 0*
E1 multiplexing turned off
E1 multiplexing turned on
EE1 = 1
E1 Polarity (Global parameter)
E1P = 0*
E1P = 1
E1 is a high-going pulse
E1 is a low-going pulse
There is no E1 output unless CMODE = 1.
Debounce for hook switch (Global parameter)
DSH = 0–15 Debounce period in ms
DSH contains the debouncing time (in ms) of the CD1 data (usually hook switch) entering the Real Time
Data register described earlier. The input data must remain stable for the debouncing time in order to
change the appropriate real time bit.
Default = 8 ms
Double PCLK Operation (Global parameter) - Program the same in both four channel groups
DPCK = 0*
DPCK = 1
Double PCLK operation is off. PCLK and PCM data at same rate.
Double PCLK enabled. PCLK operates at twice the PCM data rate.
Enable Chopper (Global parameter)
ECH = 0*
ECH = 1
Chopper output (CHCLK) turned off
Chopper output (CHCLK) turned on
* Power Up and Hardware Reset (RST) Value = 20h.
CDh Read Transmit PCM Data (PCM/MPI Mode Only)

Upper Transmit Data
Reserved for future use. Always write as 0, but 0 is not guaranteed when read.
XDAT contains A-law or µ-law transmit data in Companded mode.
XDAT contains upper data byte in Linear mode with sign in XDAT7.
