Value after reset: FE
CIR1
CODR1 ... C/I-Code 1 Receive
CICW, CI1E ... C/I-Channel Width, C/I-Channel 1 Interrupt Enable
These two bits contain the read back values from CIX1 register (see below).

Value after reset: FE
CIX1
CODX1 ... C/I-Code 1 Transmit
Bits 7-2 of C/I-channel 1.
CICW... C/I-Channel Width
CICW selects between a 4 bit (’0’) and 6 bit (’1’) C/I1 channel width.
The C/I1 handler always reads and writes 6-bit values but if 4-bit is selected, the higher
two bits are ignored for interrupt generation. However in write direction the full CODX1
code is transmitted, i.e. the host must write the higher two bits to “1”.
CI1E ... C/I-Channel 1 Interrupt Enable
Interrupt generation ISTA.CIC of CIR0.CIC1 is enabled (1) or masked (0).
