23 / 114 page  REJ03B0254-0110 Rev.1.10 Page 23 of 111 Jun 23, 2010 R32C/117 Group 1. Overview Notes: 1. Port P9_1 in the 100-pin package is an input-only port. 2. Ports P9_0, P9_2, and P11 to P15 are available in the 144-pin package only. Table 1.18 Pin Definitions and Functions (3/4) Function Symbol I/O Description I/O port (1, 2) 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_4, P12_0 to P12_7, P13_0 to P13_7, P14_3 to P14_6, P15_0 to P15_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 1.20 “Pin Specifications” for details Input port (2) P9_1 (for 100-pin package) P14_1 (for 144- pin package) I Input port in CMOS Pull-up resistor is selectable.
