(10) P90 to P96 (Port 9) … Input/Output
Port 9 is a 7-bit I/O port in which input or output can be set for each port pin individually.
Besides functioning as an I/O port, in control mode, P90 to P96 operate as serial interface
(CSI31
Note
, CSIB1
Note
). Additionally external interrupt request signal inputs are available in port
input mode.
The operation mode can be specified by the port 9 mode control register (PMC9) to port or control
mode for each port pin individually.
(a) Port mode
P90 to P96 can be set to input or output in 1-bit units using the port 9 mode register (PM9).
(i) INTP9, INTP10, INTP11 (Interrupt request from peripherals) … Input
These are external interrupt request input pins, which are simultaneously enabled in port input
mode.
(b) Control mode
P90 to P96 can be set to port or control mode in 1-bit units using the PMC9 register.
(i) SO31 (Serial output) … Output
Note
This pin outputs CSI31 serial transmit data.
(ii) SI31 (Serial input) … Input
Note
This pin inputs CSI31 serial receive data.
(iii) SCK31 (Serial clock) … I/O
Note
This is the CSI31 serial clock I/O pin.
(iv) SCS310 to SCS313 (Serial chip select) … Output
Note
These pins output CSI31 serial chip select signals.
(v) SSB1 (Serial slave select input) … Input
Note
This pin inputs CSIB1 slave select signal.
