Rev. P1.10
0 = Normal. No RTS control function.
1 = Auto RTS control function
MR2 A/B
Mode register 2. This register is accessed after any read
or write operation to MR1 A/B register is performed.
Access to MR2 A/B does not change the pointer.
MR2 A/B Bits 3-0.
Stop bit length
0000 = 0.563
0001 = 0.625
0010 = 0.668
0011 = 0.750
0100 = 0.813
0101 = 0.875
0110 = 0.938
0111 = 1.000
1000 = 1.563
1001 = 1.625
1010 = 1.668
1011 = 1.750
1100 = 1.813
1101 = 1.875
1110 = 1.938
1111 = 2.000
MR2 A/B Bit-4.
Auto CTS flow control
0 = Normal. No CTS control function
1 = Auto CTS control function.
MR2 A/B Bit-5.
Transmit RTS control.
0 = Normal. No control function
1 = Transmit RTS function enable.
MR2 A/B Bit 7-6.
Channel Mode.
0 0 = Normal
0 1 = Automatic Echo
1 0 = Local Loopback
1 1 = Remote Loopback
CLOCK SELECT REGISTER-CSR A/B
Transmit / Receive baud rates can be selected via this
register.
CSR A/B Bits 3-0.
Transmit clock select (see baud rate table)
CSR A/B Bits 7-4.
Receive clock select (see baud rate table)
MISCELLANEOUS COMMAND REGISTER CR A/B
CR A/B register is used to supply commands to A/B
channels. Multiple commands can be specified in a
single write to CR A/B as long as commands are non-
conflicting.
CR A/B Bits 1-0.
Receiver Commands
0 0 = No Action, Stays in Present Mode
0 1 = Receiver Enabled
1 0 = Receiver Disabled
1 1 = Not Used
CR A/B Bits 3-2.
Transmitter Commands
0 0 = No Action, Stays in Present Mode
0 1 = Transmitter Enabled
1 0 = Transmitter Disabled
1 1 = Not Used
CR A/B Bits 7-4.
Miscellaneous Commands.
0 0 0 0 = No Command.
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 Channels Break-Change Interrupt.
Clears channel A/B break detect change bit
in the interrupt status register (ISR Bit-2).
0 1 1 0 = Start Break. Forces the transmitter output to
go low and stay low. If transmitter is empty
the start of the break condition will be de-
layed up to two bit times. If transmitter is
active, the break begins when transmission
of the character is completed. All contents of
the FIFO has to be transmitted before break
signal takes place. Transmitter must to be
enabled for this command to be accepted.
0 1 1 1 = Stop Break. Transmit output will go high
within two bit times.
1 0 0 0 = Set -RTS output to low.
1 0 0 1 = Reset -RTS output to high.
