applied via CRB. After reading or writing MR0B, the pointer will
point to MR1B.
The bit definitions for this register are identical to MR0A, except that
all control actions apply to the Channel B receiver and transmitter
and the corresponding inputs and outputs. MR0B[3:0] are reserved.
MR1B – Channel B Mode Register 1
MR1B is accessed when the Channel B MR pointer points to MR1.
The pointer is set to MR1 by RESET or by a ‘set pointer’ command
applied via CRB. After reading or writing MR1B, the pointer will
point to MR2B.
The bit definitions for this register are identical to MR1A, except that
all control actions apply to the Channel B receiver and transmitter
and the corresponding inputs and outputs.
MR2B – Channel B Mode Register 2
MR2B is accessed when the Channel B MR pointer points to MR2,
which occurs after any access to MR1B. Accesses to MR2B do not
change the pointer.
The bit definitions for mode register are identical to the bit
definitions for MR2A, except that all control actions apply to the
Channel B receiver and transmitter and the corresponding inputs
and outputs.
CSRA – Channel A Clock Select Register
CSRA[7:4] – Channel A Receiver Clock Select
This field selects the baud rate clock for the Channel A receiver.
The field definition is shown in Table 5.

The receiver clock is always a 16X clock except for CSRB[7:4] = 1111.
CSRA[3:0] – Channel A Transmitter Clock Select
This field selects the baud rate clock for the Channel A transmitter.
The field definition is as shown in Table 5, except as follows:
CSRA[3:0]
ACR[7] = 0
ACR[7] = 1
1110
1111

CSRB – Channel B Clock Select Register
CSRB[7:4] – Channel B Receiver Clock Select
This field selects the baud rate clock for the Channel B receiver.
The field definition is as shown in Table 5, except as follows:
CSRB[7:4]
ACR[7] = 0
ACR[7] = 1
1110
1111
IP6-16X
IP6-1X
IP6-16X
IP6-1X
The receiver clock is always a 16X clock except for CSRB[7:4] = 1111.
CSRB[3:0] – Channel B Transmitter Clock Select
This field selects the baud rate clock for the Channel B transmitter.
The field definition is as shown in Table 5, except as follows:
CSRB[3:0]
ACR[7] = 0
ACR[7] = 1
1110
