P63
D
(CMOS/H)
General-purpose I/O port
A pull-up resistor can be assigned (RD63=’1’) by using the pull-up resistor
setting register (RDR6). (D63=’1’: Invalid when set as output)
PPG00
PPG00 output when PPG is enabled
63
61
P64
D
(CMOS/H)
General-purpose I/O port
A pull-up resistor can be assigned (RD64=’1’) by using the pull-up resistor
setting register (RDR6). (D64=’1’: Invalid when set as output)
PPG01
PPG01 output when PPG is enabled
64
62
P65
D
(CMOS/H)
General-purpose I/O port
A pull-up resistor can be assigned (RD65=’1’) by using the pull-up resistor
setting register (RDR6). (D65=’1’: Invalid when set as output)
CKOT
CKOT output during CKOT operation
65
63
TX
I
IEBus output when IEBus is enabled
66
64
RX
J
IEBus input when IEBus is enabled
67 to 69
65 to 67
P90 to P92
F
(CMOS/H)
General-purpose I/O port
TIN0 to TIN2
Event input pins for reload timers 0,1 and 2. As these inputs are used con-
tinuously during reload timer input operation, outputs to these pins from
other functions must be avoided unless performed intentionally.
IN0 to IN2
Input capture channels 0 - 2 trigger inputs
70
68
P93
F
(CMOS/H)
General-purpose I/O port
TOT0
Output pins for reload timer 0. This function applies when the output for
reload timers 0 is enabled.
IN3
Input capture channel 3 trigger input
71 to 72
69 to 70
P94 to P95
F
(CMOS/H)
General-purpose I/O port
TOT1, TOT2
Output pins for reload timers 1 and 2. This function applies when the out-
puts for reload timers 1 and 2 are enabled.
OUT0, OUT1
Output comparison channels 0 - 1 event outputs
