REJ03B0299-0100 Rev.1.00 Page 22 of 127 Jul 16, 2010 R32C/118A Group 1. Overview Note: 1. Ports P16 to P19 are available in the 176-pin package only. Table 1.17 Pin Definitions and Functions (3/4) I/O port (1) P0_0 to P0_7, P1_0 to P1_7, P2_0 to P2_7, P3_0 to P3_7, P4_0 to P4_7, P5_0 to P5_7, P6_0 to P6_7, P7_0 to P7_7, P8_0 to P8_4, P8_6, P8_7, P9_0 to P9_7, P10_0 to P10_7, P11_0 to P11_7, P12_0 to P12_7, P13_0 to P13_7, P14_3 to P14_7, P15_0 to P15_7, P16_0 to P16_7, P17_0 to P17_7, P18_0 to P18_7, P19_0 to P19_7 I/O I/O ports in CMOS. Each port can be programmed to input or output under the control of the direction register. Some ports are 5 V tolerant inputs. Pull-up resistors and N-channel open drain setting can be enabled on some ports. Refer to Table 1.19 “Pin Specifications” for details Input port P14_1 I Input port in CMOS Pull-up resistor is selectable. Refer to Table 1.19 “Pin Specifications” for details Timer A TA0OUT to TA4OUT I/O Timers A0 to A4 input/output TA0IN to TA4IN I Timers A0 to A4 input Timer B TB0IN to TB5IN I Timers B0 to B5 input Three-phase motor control timer output U, U, V, V, W, W O Three-phase motor control timer output Serial interface CTS0 to CTS10 I Handshake input RTS0 to RTS10 O Handshake output CLK0 to CLK10 I/O Transmit/receive clock input/output RXD0 to RXD10 I Serial data input TXD0 to TXD10 O Serial data output I2C bus (simplified) SDA0 to SDA6 I/O Serial data input/output SCL0 to SCL6 I/O Transmit/receive clock input/output Serial interface special functions STXD0 to STXD6 O Serial data output in slave mode SRXD0 to SRXD6 I Serial data input in slave mode SS0 to SS6 I Input to control serial interface special functions |
