(2) P10 to P15 (Port 1) ··· 3-state I/O
Port 1 is a 6-bit I/O port in which input and output pins can be specified bitwise.
P10 to P15 can function as I/O port pins and can also operate as input or output pins for the serial interface.
These pins can be set bitwise to port mode or a control mode.
P10 to P12, P14, and P15 can select normal output and N-ch open drain output.
(a) Port mode
P10 to P15 can be set bitwise as input or output pins according to the contents of port 1 mode register
(PM1).
(b) Control modes
P10 to P15 can be set bitwise to port mode or a control mode according to the contents of the port 1 register
(P1) or port 1 mode register (PM1).
(i)
SI0, SI1 (Serial Input 0, 1) ··· input
These pins accept input of the serial receive data of CSI0 and CSI1.
(ii) SO0, SO1 (Serial Output 0, 1) ··· output
These pins accept output of the serial transmit data of CSI0 and CSI1.
(iii) SCK0, SCK1 (Serial Clock 0, 1) ··· 3-state I/O
These are the serial clock I/O pins for CSI0 and CSI1.
(iv) SDA (Serial Data) ··· I/O
This is the serial transmit/receive data I/O pin for I
(v) SCL (Serial Clock) ··· I/O
This is the serial clock I/O pin for I
(vi) RXD0 (Receive Data 0) ··· input
This is the input pin for UART0 serial receive data.
(vii) TXD0 (Transmit Data 0) ··· output
This is the output pin for UART0 serial transmit data.
(viii) ASCK0 (Asynchronous Serial Clock 0) ··· input
This is the input pin for UART0 serial baud rate clock.
