43 / 180 page  TMP93CS32 2004-02-10 93CS32-41 3.5 Functions of Ports The TMP93CS32 has 49 bits for I/O ports. These port pins have I/O functions for the built-in CPU and internal I/Os as well as general-purpose I/O port functions. Table 3.5.1 lists the function of each port pin. Table 3.5.2 lists I/O registers and specification. Resetting makes the port pins listed below function as general-purpose I/O ports. I/O pins programmable for input or output are set to input ports. To set port pins for built-in functions, a program is required. Table 3.5.1 Functions of Ports (PU = with programmable pull-up resistor) Port Name Pin Name Pin No. Direction R Direction Setting Unit Pin Name for Built-in Function Port 0 P00 to P07 8 I/O − Bit AD0 to AD7 Port 1 P10 to P17 8 I/O − Bit AD8 to AD15/A8 to A15 Port 2 P20 to P27 8 I/O PU Bit A0 to A7/A16 to A23 Port 3 P30 P31 P32 P35 1 1 1 1 Output Output I/O I/O − − PU − (Fixed) (Fixed) Bit Bit RD WR HWR INT0 Port 4 P41 P42 P43 P44 P45 P46 P47 1 1 1 1 1 1 1 I/O I/O I/O I/O I/O I/O I/O − − − − − − − Bit Bit Bit Bit Bit Bit Bit TO3 TI4/INT4 TI5/INT5 TO4 TI6/INT6 TI7/INT7 TO6 Port 5 P50 to P52 P53 P54, P55 3 1 2 Input Input Input − − − (Fixed) (Fixed) (Fixed) AN0 to AN2, AN3/ ADTRG AN4, AN5 Port 6 P60 P61 P62 P63 P64 P65 1 1 1 1 1 1 I/O I/O I/O I/O I/O I/O PU PU PU PU PU PU Bit Bit Bit Bit Bit Bit TXD0 RXD0 SCLK0/ 0 CTS TXD1 RXD1 SCLK1/ 1 CTS Port 7 P70 P71 1 1 I/O I/O − − Bit Bit WAIT /(High current output) (High current output) |
