3.2 Control Register Overview
Table 3-2
lists the 52 control registers of the CN8223. Control registers are realized as latches within the
CN8223 and are programmed by a write operation from the microprocessor. No initialization is provided for
operational purposes. All registers must be initialized as required for each application by the microprocessor. A
reset signal on the RESET pin (pin 118) resets counters and framer state machines. RESET does not affect
control register contents.
Control bits that do not have a defined function are reserved and must be written to 0. All control registers
can be read to verify contents, except those control bits whose functions cause single events and are, therefore,
not latched.
Control registers in this section have been ordered by function: 7 control configurations, 19 control
transmitter functions, 22 control receiver functions, and 4 enable interrupts.
