Description

79

PF0/TCI0

[TCI0] External clock input of timer 0.

D

[PF0] General input/output port

80

SI2/PF1

[SI2] Data input of UART2.This function is active when data in-

D

put of UART2 is allowed.

[PF1] General input/output port

81

SO2/PF2

[SO2] Data output of UART2.This function is active when data

output of UART2 is allowed.

D

[PF2] General input/output port. This function is active when

data output of UART2 is disallowed.

82

SC2/PF3/ATG

[SC2] Clock input of UART2

[ATG]External trigger input of A/D converter The input is used

D

whenever necessary if a function concerned is selected.

Output of other functions must be suspended if not on purpose.

[PF3] General input/output port

83 to 90

AN0/PJ0

AN1/PJ1

AN2/PJ2

AN3/PJ3

AN4/PJ4

AN5/PJ5

AN6/PJ6

AN7/PJ7

[AN0 to AN7] Analog input of A/D converter.

This function is active when analog input is specified in AIC reg-

ister.

E

[PJ0 through PJ7] General input/output ports

91

AVCC



VCC power supply for A/D converter

92

AVRH

Reference voltage of A/D converter (high potential side). Be



sure to turn on or off this terminal with a potential higher than

AVRH applied to VCC.

93

AVSS/AVRL



A/D converter VSS power source and reference voltage (low po-

tential side).

94 to 96

VCC



Power sources of digital circuits. Be sure to connect power

source to all terminals when the device is used.

97 to 100

VSS



Ground level of digital circuits.

Note : Most of the above terminals multiplex inputs and outputs of I/O ports and resources, as indicated as “XXXX/

PXX”. If the outputs of ports and resources conflict with each other on the terminals, resources take prefer-

ences.
