7 / 68 page 7/68 ST10R172L - PIN DESCRIPTION P4.0– P4.7 23-26 29-32- I/O 5T An 8-bit bidirectional I/O port. Port 8 is bit-wise programmable for input or output via direction bits. For a pin configured as input, the output driver is put into high-impedance state. Port 4 can be used to output the segment address lines for external bus configuration. 23 O 5T P4.0 A16 Least Significant Segment Addr.

Line O 5T SSPCLK SSP Clock Output Line RD 33 O 5T External Memory Read Strobe. RD is activated for every exter- nal instruction or data read access. WR/ WRL 34 O 5T External Memory Write Strobe. In WR-mode, this pin is acti- vated for every external data write access. In WRL-mode, this pin is activated for low byte data write accesses on a 16-bit bus, and for every data write access on an 8-bit bus. See WRCFG in the SYSCON register for mode selection. READY/ READY 35 I 5T Ready Input. Active level is programmable. When the Ready function is enabled, the selected inactive level at this pin dur- ing an external memory access will force the insertion of mem- ory cycle time waitstates until the pin returns to the selected active level. Polarity is programmable. Table 1 Pin definitions 1 |
