Description

-
Baud rate generator set select.
This bit selects one of two sets of baud rates to be generated by the BRG (see
The selected set of rates is available for use by the channel A and B receivers
and transmitters as described for CSRA in Table 34 and for CSRB in Table 37.
Baud rate generator characteristics are given in Table 36.
6 to 4
-
Counter/timer mode and clock source select.
This eld selects the operating mode of the counter/timer and its clock source
as shown in Table 54.
3 to 0
-
IP3, IP2, IP1 and IP0 change-of-state interrupt enable.
0 = off
1 = enabled
This eld selects which bits of the input port change register (IPCR) cause the
input change bit in the interrupt status register (ISR [7]) to be set. If a bit is in
the enabled state the setting of the corresponding bit in the IPCR will also
result in the setting of ISR [7], which results in the generation of an interrupt
output if IMR [7] = 1. If a bit is in the off state, the setting of that bit in the IPCR
has no effect on ISR [7].
