Data Sheet
2A
No reset value.
TWIST Signal twist for DTMF tone
In order to obtain a minimal signal twist T the parameter TWIST can be calculated by the
following formula:
Value range: [0x1000..0x5000] = [8.53dB..1.54dB]
Note: TWIST must be in the range [4096,20480]
2B
No reset value.
MIN
Note: Values outside the given range are reserved and must not be used.
