Function
QFP*
84
P56
C
General-purpose I/O port
This function is valid in single-chip mode. This function is valid in
modes where the external bus is valid.
RD
Read strobe output pin for the data bus
This function is valid in modes where the external bus is enabled.
85
P57
B
General-purpose I/O port
This function is always valid.
When these pins are open in input mode, through current may leak in
stop mode/reset mode, be sure to fix these pins to V
CC
/V
SS
level to
use these pins in input mode.
WI
RAM write disable request input
During this operation, the input may be used suddenly at any time;
therefore, it is necessary to stop output by other fuctions on this pin,
except when using it for output deliberately.
46 to 53
P60 to P67
F
Open-drain I/O ports
This function is valid when the analog input enable register
specification is “port”.
AN00 to AN07
10-bit A/D converter analog input pins
This function is valid when the analog input enable register
specification is “analog input”.
17 to 24
P70 to P77
C
General-purpose I/O ports
This function is valid when the output specification for DOT0 to DOT7
is “disabled”.
DOT0 to DOT7
This function is valid when OCU (output compare unit) output is
enabled.
25 to 30
P80 to P85
C
General-purpose I/O ports
This function is valid when the output specification for TOT0 to TOT5
is “disabled”.
TOT0 to TOT5
16-bit reload timer output pins (TOT0 to TOT5)
31,
32
P86,
P87
C
General-purpose I/O ports
This function is valid when the PPG0, and PPG1 output specification
is “disabled”.
PPG0,
PPG1
16-bit PPG timer output pins
This function is valid when the PPG control/status register
specification is “PPG output pins”.
34 to 41
P90 to P97
F
Open-drain I/O ports
This function is valid when the analog input enable register
specification is “port”.
AN08 to AN15
10-bit A/D converter analog input pins
This function is valid when the analog input enable register
specification is “analog input”.
