PROGRAMMING THE HOST INTERFACE
Writing control words into the appropriate registers programs the
operation of the DUART. Operational feedback is provided via status
registers that can be read by the CPU. The addressing of the
registers is described in the Register Map.
The contents of certain control registers are initialized to zero on
RESET. Care should be exercised if the contents of a register are
changed during operation, since certain changes may cause
operational problems.
For example, changing the number of bits per character while the
transmitter is active may cause the transmission of an incorrect
character. In general, the contents of the MR, the CSR, and the
OPCR should only be changed while the receiver(s) and
transmitter(s) are not enabled, and certain changes to the ACR
should only be made while the C/T is stopped.
Each channel has 3 mode registers (MR0, 1, 2) which control the
basic configuration of the channel. Mode, command, clock select,
and status registers are duplicated for each channel to provide total
independent operation and control. Refer to Table 2 for register bit
descriptions.
