7.1
The basic operation mode (serial or register based) can be selected individually for
receive and transmit direction.
If RSIG is configured on one of the RX multifunction ports RPA...RPC, serial RX-CAS
data on RSIG are used automatically. If XSIG is configured on one of the TX
multifunction ports XPA, RPB, serial TX-CAS data on XSIG are used automatically and
XS1...16 registers are ignored.
7.2
In T1 mode the function to force all robbed bits to “one” can be selected to be not
performed in CAS cleared channels. This mode is selected by setting register bit
XC0.BRFO1 = 1.
7.3
In T1 mode the bit robbing idle function is selectable by register bit XC0.BRIF. If this bit
is set, bit robbing information is not overwritten by the idle code in idle channels.
