7. Pin function
External pin function of MB86R01 is described below.
7.1. Pin Multiplex
This LSI adopts pin multiplex function, and a part of external pin function is multiplexed.
The external pin function is categorized into following five groups. Each group is able to set the external
pin function individually; therefore, the function can be flexibly set depending on the peripheral I/O
resource to be used.
1. Pin multiplex group #1 (setting pin: MPX_MODE_1[1:0])
• Mode 0: Pin related to DISPLAY1
• Mode 1: Pin related to external bus interface
• Mode 2: Pin related to I2S0, GPIO, and DISPLAY0 data width extension
2. Pin multiplex group #2 (setting register: CMUX_MD.MPX_MODE_2[2:0])
• Mode 0: Pin related to CAP1, CAP0 synchronizing signal, PWM, and I2S2
• Mode 1: Pin related to CAP1 (NRGB666)
• Mode 2: Pin related to GPIO, CAN, I2S1, MediaLB, and I2S2
• Mode 3: Pin related to GPIO, CAN, I2S1, MediaLB, and SPI
• Mode 4: Pin related to GPIO, CAN, I2S1, MediaLB, and I2S2 (input)
3. Pin multiplex group #3 (setting pin: USB_MODE)
• Mode 0: Pin related to USB 2.0 host
• Mode 1: Pin related to USB 2.0 function
4. Pin multiplex group #4 (setting register: CMUX_MD.MPX_MODE_4[1:0])
• Mode 0: Pin related to IDE
• Mode 1: Pin related to I2S1, CAN, GPIO, and PWM
5. Pin multiplex group #5 (setting pin: MPX_MODE_5[1:0])
• Mode 0: Pin related to ETM
• Mode 1: Pin related to UART3, UART4, and UART5
• Mode 2: Pin related to UART3, UART4, and PWM
Note:
Mode should be changed when each pin is not in operation.
PWM, I2S1, and CAN pins may be duplicated and allocated to external pin depending on group
combination; in this case, use either of them. For unused pin, follow the procedure in 1.6.27,
unused pin with pin multiplex function in the duplex case.
