8 / 88 page  MB91220/S Series 8 (Continued) Pin No. Pin name I/O circuit type* Function 123 P51 I General-purpose I/O port: Valid when the data output specification is prohibited on LIN-UART2. SOT4 LIN-UART2 data output: Valid when the data output specification is permitted on LIN-UART2. CS1X Chip select 1 output: Valid when the output specification is permitted on chip select 1. 124 P52 I General-purpose I/O port: Valid when clock output is prohibited on LIN-UART2. SCK4 LIN-UART2 clock input/output: Valid when the clock output specification is permitted on LIN-UART2. CS2X Chip select 2 output: Valid when the output specification is permitted on chip select 2. 125 P53 M General-purpose I/O port: Valid when the data input specification is prohibited on LIN-UART3. SIN5 LIN-UART3 data input. Because this input is used as necessary while LIN- UART3 is used for input operation, the port output needs to be disabled except when it is used intentionally. CK1 External clock input for free-run timer 1 CS3X Chip select 3 output: Valid when the output specification is permitted on chip select 3. 130 P54 I General-purpose I/O port: Valid when data output specification is prohibited on LIN-UART3. SOT5 LIN-UART3 data output: Valid when the data output specification is permitted on LIN-UART3. RDX External bus read strobe output: Valid at the external bus mode. 131 P55 I General-purpose I/O port: Valid when clock output is prohibited on LIN-UART3. SCK5 LIN-UART3 clock input/output: Valid when the clock output specification is permitted on LIN-UART3. WR0X External bus write strobe output: Valid when the WR0X output is permitted at the external bus mode. 132 P56 I General-purpose I/O port OUT0 Output compare output WR1X External bus write strobe output: Valid when the WR1X output is permitted at the external bus mode. 133 P57 J General-purpose I/O port OUT1 Output compare output RDY External ready input: Valid when the external ready input specification is permitted. |
