Function
LQFP-120 *1
QFP-120 *2
29 to 32
P64 to P67
F
In single chip mode these are general-purpose I/O ports. When set for
input they can be set by the pull-up resistance register (RDR6). When set
for output this setting will be invalid.
OUT0 to
OUT3
These are also the output compare ch.0 to ch.3 event output pins. This
function is valid when the respective channel(s) are enabled for output.
35 to 37
P70 to P72
E
These are general purpose I/O ports.
40,41
P73,P74
I
These are general purpose I/O ports.
DA0,DA1
These are also the D/A converter ch.0,1 analog signal output pins.
46 to 53
P80 to P87
K
These are general purpose I/O ports.
AN0 to AN7
These are also A/D converter analog input pins. This function is valid
when analog input is enabled.
55 to 62
P90 to P97
E
These are general purpose I/O ports.
CS0 to CS7
These are also chip select signal output pins. This function is valid when
chip select signal output is enabled.
34
C
G
This is the power supply stabilization capacitor pin. It should be
connected externally to an 0.1 F ceramic capacitor. Note that this is
not required on the FLASH model (MB90F574/A) and MB90574B.
64
PA0
E
This is a general purpose I/O port.
AIN0
This pin is also used as count clock A input for 8/16-bit up-down counter
ch.0.
IRQ6
This pin can also be used as interrupt request input ch. 6.
65
PA1
E
This is a general purpose I/O port.
BIN0
This pin is also used as count clock B input for 8/16-bit up-down counter
ch.0.
66
PA2
E
This is a general purpose I/O port.
ZIN0
This pin is also used as count clock Z input for 8/16-bit up-down counter
ch.0.
67
PA3
E
This is a general purpose I/O port.
AIN1
This pin is also used as count clock A input for 8/16-bit up-down counter
ch.1.
IRQ7
This pin can also be used as interrupt request input ch.7.
68
PA4
E
This is a general purpose I/O port.
BIN1
This pin is also used as count clock B input for 8/16-bit up-down counter
ch.1.
69
PA5
E
This is a general purpose I/O port.
ZIN1
This pin is also used as count clock Z input for 8/16-bit up-down counter
ch.1.
