Rev. 1.31
Baud Rate Table for a 3.6864MHz clock. Data rates would double for a 7.3728MHz clock.
CLOCK SELECT REGISTER (CSRA, CSRB)
Transmit / Receive baud rates for channels A, B can be
selected via this register.
CSRA, CSRB Bits 3-0.
Transmit clock select(see baud rate table).
CSRA, CSRB Bits 7-4.
Receive clock select (see baud rate table).
COMMAND REGISTER (CRA, CRB)
CRA, CRB register is used to supply commands to A,
B channels respectively. Multiple commands can be
specified in a single write to CRA, CRB as long as
commands are non-conflicting.
CRA, CRB Bits 1-0:
Receiver Commands.
0 0 = No Action, Stays in Present Mode (default)
0 1 = Receiver Enabled
1 0 = Receiver Disabled
1 1 = Don’t Use
CRA, CRB Bits 3-2: Transmitter Commands.
0 0 = No Action, Stays in Present Mode (default)
0 1 = Transmitter Enabled
1 0 = Transmitter Disabled
1 1 = Don’t Use
CRA, CRB Bits 7-4:
Miscellaneous Commands.
0 0 0 0 = No Command (default).
0 0 0 1 = Reset MR Pointer to MR1.
0 0 1 0 = Reset Receiver. Receiver is disabled and
FIFO is flushed.
0 0 1 1 = Reset Transmitter. Transmitter is disabled
and FIFO is flushed.
0 1 0 0 = Reset Error Status. Clears channel A/B,
break, parity, and over-run error bits in the
status register.
0 1 0 1 = Reset Channel's Break-Change Interrupt.
Clears channel A/B break detect change bit
in the interrupt status register (ISR bit-2 for
channel A and ISR bit-6 for channel B).
* Baud Rate is independent of MR0 bit-0 & bit-2 and ACR bit-7 settings.
