P00, TXD1A

 

 

can be selected. Pull-up resistors can be

SBO1B

45

 

 

P73, TXD1B

 

 

selected by the P0PLU register, the P5PLU

SBO3

P51, SDA3

register and the P7PLUD register. Select output

 

 

 

 

 

mode by the P0DIR register, the P5DIR register

 

 

 

 

 

and the P7DIR register, and serial data output

 

 

 

 

 

mode by serial mode register 1 (SC0MD1,

 

 

 

 

 

SC1MD1, SC3MD1). These can be used as

 

 

 

 

 

normal I/O pins when the serial interface is not

 

 

 

 

 

used.

 

 

 

 

 

 

SBI0A

reception data input

P71, RXD0B

1, 3. Pll-up resistors can be selected by the

SBI1A

16

 

pins

P01, RXD1A

P0PLU register, the P5PLU register and the

 

 

P7PLUD register. Select input mode by the

 

 

 

 

SDA4A

 

 

 

 

P0DIR register, the P5DIR register, the P7DIR

SBI1B

46

 

 

P74, RXD1B

register and serial input mode by the serial mode

SBI3

32

 

 

P50

register 1 ( SC0MD1, SC1MD1, SC3MD1). These

 

 

 

 

 

can be used as normal I/O pins when the serial

 

 

 

 

 

interface is not used.

 

 

 

 

 

 

SBT0A

20

I/O

Serial interface

P50

Clock I/O pins for serial interfaces 0, 1,3. The

SBT0B

50

 

clock I/O pins

P72

output configuration, either CMOS push-pull or n-

 

 

channel open-drain can be selected. Pull-up

SBT1A

17

 

 

P02, SCL4A

 

 

resistors can be selected by the P0PLU resister

SBT1B

47

 

 

P75

 

 

and the P5PLU register and the P7PLUD

SBT3

34

 

 

P52, SCL3

register. Select clock I/O for each communication

 

 

 

 

 

mode by the P0DIR register, the P5DIR register,

 

 

 

 

 

the P7DIR register and serial mode register 1

 

 

 

 

 

( SC0MD1, SC1MD1, SC3MD1). These can be

 

 

 

 

 

used as normal I/O pins when the serial interface

 

 

 

 

 

is not used.

 

 

 

 

 

 

TXD0A

18

Output

UART transmission

SBO0A, P03

In the serial interface in UART mode, these pins

TXD0B

48

 

data output pins

SBO0B, P70

are configured as the transmission data output

 

 

pins. The output configuration, either CMOS

TXD1A

15

 

 

SBO1A, P00

 

 

push-pull or n-channel open-drain can be

TXD1B

45

 

 

SBO1B, P73

selected. Pull-up resistors can be selected by

 

 

 

 

 

the P0PLU register and the P7PLUD register.

 

 

 

 

 

Select output mode by the P0DIR register and the

 

 

 

 

 

P7DIR register, and serial data output by serial

 

 

 

 

 

interface 1 mode register 1 ( SC0MD1, SC1MD1).

 

 

 

 

 

These can be used as normal I/O pins when the

 

 

 

 

 

serial interface is not used.
