P1OC Register (0xE4)

Bit

Field

Type

Initial

Description

P06OC

R/W

0: Switch P0.6 (URX) to input mode (required)

1: Switch P0.6 (URX) to open-drain mode

P05OC

R/W

0: Switch P0.5 (UTX) to push-pull mode

1: Switch P0.5 (UTX) to open-drain mode

Else

Refer to other chapter(s)

* Setting P06OC as high causes URX cannot receive data.

P0M Register (0xF9)

Bit

Field

Type

Initial

Description

P06M

R/W

0: Set P0.6 (URX) as input mode (required)

1: Set P0.6 (URX) as output mode

P05M

R/W

0: Set P0.5 (UTX) as input mode

1: Set P0.5 (UTX) as output mode (required)

Else

Refer to other chapter(s)

* The URX and UTX respectively require input and output mode selection to receive/transmit data appropriately.

P0 Register (0x80)

Bit

Field

Type

Initial

Description

P06

R/W

This bit is available to read at any time for monitoring

the bus statue.

P05

R/W

0: Set P0.5 (UTX) always low

1: Make P0.5 (UTX) can output UART data (required)

Else

Refer to other chapter(s)

* Setting P05 initially high because UART block drive the shared pin low signal only.
