Description

51

CS3/PA3/SO1

52

CS4/PA4/SI1

53

CS5/PA5/SC1

Chip select 3, 4, 5 output (Low active).

[PA3,4,5] Available as general input/output ports when channel

D

1 of chip select UART is not used.

[SO1,SI1,SC1] Data output, data input, and clock terminals of

UART1. Active when UART1 operation is allowed.

54

CLK/PA6

System clock output. Outputs a same clock as the same fre-

D

quency of external bus operation.

[PA6] Available as general input/output ports it is not used.

OC1/PG5

61

OC2/PG6

62

OC3/PG7

[OCPA0 to 3] PPG timer outputs. The function is active when

PPG timer output is allowed.

D

[OC0 to 3] Output comparison output. The function is active

when output comparison output is allowed. [PB0-7] Available as

general input/output ports it is not used.

63

MD0

64

MD1

65

MD2

Mode terminals 0 through 2. The terminals specify basic opera-

B

tion mode of MCU.

Use the terminals by connecting them directly to VCC or VSS.

Clock (oscillation) output.

68

RST

C

External reset input.

69

HST

C

Hardware standby input.

70

P86/ALE

D

[ALE] Address latch signal output. The function is active when

ALE output of EPCR is allowed.

INT0/PE0

71

INT1/PE1

72

INT2/PE2

INT3/PE3

[INT0,1,2,3] External interrupt request inputs. The input is used

whenever necessary if external interrupt is allowed. Output of

D

other functions must be suspended if not on purpose.

75

INT4/PE4/TCI1

76

INT5/PE5/SC0

[INT4,5] External interrupt request inputs.The input is used

whenever necessary if concerned external interrupt is allowed.

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

D

[TCI1] External clock input of timer 1. [SC0] Clock input of

UART0.

[PE4,5] General input/output port

77

SI0/PE6

[SI0] Data input of UART0.This function is active when data in-

D

put of UART0 is allowed.

[PE6]General input/output port

78

SO0/PE7

[SO0] Data output of UART0.This function is active when data

D

output of UART0 is allowed.

[PE7] General input/output port
