■ PIN DESCRIPTIONS
Pin No.
LQFP-120*1
QFP-120*2
Pin Name
Circuit
Type
Function
92, 93
X0, X1
A Oscillator pin
74, 73
X0A, X1A B Sub-oscillator pin
89 to 87
MD0 to
MD2
Input pins for setting the operation mode.
C/P
Connect directly to VCC or VSS.
MB90522B and MB90523B of mask ROM have a built-in pull down resistor
only for MD2 pin, and the circuit type of MD2 pin is “P”.
External reset input pin
90
RST
C/O MB90522B and MB90523B of mask ROM have a built-in pull up resistor,
and its circuit type is “O”.
86
HST
C Hardware standby input pin
95 to 101
P00 to
P06
General-purpose I/O ports
The settings in the pull-up resistor setup register (RDR0) are enabled
when ports are set as inputs.
D The RDR0 settings are ignored when ports are set as outputs.
INT0 to
INT6
Event input pins for ch.0 to ch.6 of the DTP/external interrupt circuit
General-purpose I/O port
102
P07
D
The settings in the pull-up resistor setup register (RDR0) are enabled when
ports are set as inputs.
The RDR0 settings are ignored when ports are set as outputs.
103 to 110
P10 to
P17
General-purpose I/O ports
The settings in the pull-up resistor setup register (RDR1) are enabled when
ports are set as inputs.
D The RDR1 settings are ignored when ports are set as outputs.
WI0 to
WI7
Event input pins for the wakeup interrupts.
P20, P21,
P22, P23
General-purpose I/O ports
111, 112,
113, 114 IN00, IN01,
E
Trigger input pins for input capture units (ICU) 0 and 1.
Input operates continuously when channels 0 and 1 of input capture units
IN10, IN11
(ICU) 0 and 1 are operating. Accordingly, output to the pins from other func-
tions that share this pin must be suspended unless performed intentionally.
P24
General-purpose I/O port
115
AIN0
E Also can be used as the count clock A input to 8/16-bit up/down counter/
timer 0.
P25
General-purpose I/O port
116
BIN0
E Also can be used as the count clock B input to 8/16-bit up/down counter/
timer 0.
