Pin Function Controller (PFC) Rev.5.00 Sep. 27, 2007 Page 433 of 716 REJ09B0398-0500 Section 16 Pin Function Controller (PFC) 16.1 Overview The pin function controller (PFC) is composed of registers for selecting the function of multiplexed pins and the direction of input/output. Table 16.1 lists this LSI's multiplexed pins. The multiplex pin functions have restrictions dependent on the operating mode. Table 16.2 lists the pin functions and initial values for each operating mode. Table 16.1 Multiplexed Pins Port Function 1 (Related Module) Function 2 (Related Module) Function 3 (Related Module) Function 4 (Related Module) Pin No. A PA15 I/O (port) CK output (CPG) ⎯ ⎯ 83 A PA14 I/O (port)* RD output (BSC) ⎯ ⎯ 34 A PA13 I/O (port)* WRH output (BSC) ⎯ ⎯ 36 A PA12 I/O (port)* WRL output (BSC) ⎯ ⎯ 38 A PA11 I/O (port)* CS1 output (BSC) ⎯ ⎯ 40 A PA10 I/O (port)* CS0 output (BSC) ⎯ ⎯ 41 A PA9 I/O (port) TCLKD input (MTU) IRQ3 (INTC) ⎯ 42 A PA8 I/O (port) TCLKC input (MTU) IRQ2 (INTC) ⎯ 43 A PA7 I/O (port) TCLKB input (MTU) CS3 output (BSC) ⎯ 44 A PA6 I/O (port) TCLKA input (MTU) CS2 output (BSC) ⎯ 45 A PA5 I/O (port) SCK1 I/O (SCI) DREQ1 input (DMAC) IRQ1 input (INTC) 46 A PA4 I/O (port) TxD1 output (SCI) ⎯ ⎯ 47 A PA3 I/O (port) RxD1 input (SCI) ⎯ ⎯ 48 A PA2 I/O (port) SCK0 I/O (SCI) DREQ0 input (DMAC) IRQ0 input (INTC) 49 A PA1 I/O (port) TxD0 output (SCI) ⎯ ⎯ 50 A PA0 I/O (port) RxD0 input (SCI) ⎯ ⎯ 51 B PB9 I/O (port) IRQ7 input (INTC) A21 output (BSC) ⎯ 32 B PB8 I/O (port) IRQ6 input (INTC) A20 output (BSC) WAIT input (BSC) 31 B PB7 I/O (port) ⎯ A19 output (BSC) ⎯ 30 B PB6 I/O (port) ⎯ A18 output (BSC) ⎯ 29 B PB5 I/O (port) IRQ3 input (INTC) ⎯ RDWR output (BSC) 28 |
