9 / 161 page ST10F269Z2Qx 9/161 P2.0 - P2.7 P2.8 - P2.15 47-54 57-64 I/O 16-bit bidirectional I/O port, bit-wise programmable for input or output via direction bit. Programming an I/O pin as input forces the corresponding output driver to high impedance state. Port 2 outputs can be configured as push-pull or open drain drivers. The input threshold of Port 2 is selectable (TTL or special). The following Port 2 pins have alternate functions: 47 I/O P2.0 CC0IO CAPCOM: CC0 Capture Input / Compare Output ... ... ... ... ... 54 I/O P2.7 CC7IO CAPCOM: CC7 Capture Input / Compare Output 57 I/O P2.8 CC8IO CAPCOM: CC8 Capture Input / Compare Output I EX0IN Fast External Interrupt 0 Input ... ... ... ... ... 64 I/O P2.15 CC15IO CAPCOM: CC15 Capture Input / Compare Output I EX7IN Fast External Interrupt 7 Input I T7IN CAPCOM2 Timer T7 Count Input P3.0 - P3.5 P3.6 - P3.13, P3.15 65-70, 73-80, 81 I/O I/O I/O 15-bit (P3.14 is missing) bidirectional I/O port, bit-wise programmable for input or output via direction bit. Programming an I/O pin as input forces the corresponding output driver to high impedance state. Port 3 outputs can be configured as push-pull or open drain drivers. The input threshold of Port 3 is selectable (TTL or special). The following Port 3 pins have alternate functions: 65 I P3.0 T0IN CAPCOM Timer T0 Count Input 66 O P3.1 T6OUT GPT2 Timer T6 Toggle Latch Output 67 I P3.2 CAPIN GPT2 Register CAPREL Capture Input 68 O P3.3 T3OUT GPT1 Timer T3 Toggle Latch Output 69 I P3.4 T3EUD GPT1 Timer T3 External Up / Down Control Input 70 I P3.5 T4IN GPT1 Timer T4 Input for Count / Gate / Reload / Capture 73 I P3.6 T3IN GPT1 Timer T3 Count / Gate Input 74 I P3.7 T2IN GPT1 Timer T2 Input for Count / Gate / Reload / Capture 75 I/O P3.8 MRST SSC Master-Receiver / Slave-Transmitter I/O 76 I/O P3.9 MTSR SSC Master-Transmitter / Slave-Receiver O/I 77 O P3.10 TxD0 ASC0 Clock / Data Output (Asynchronous / Synchronous) 78 I/O P3.11 RxD0 ASC0 Data Input (Asynchronous) or I/O (Synchronous) 79 O P3.12 BHE External Memory High Byte Enable Signal WRH External Memory High Byte Write Strobe 80 I/O P3.13 SCLK SSC Master Clock Output / Slave Clock Input 81 O P3.15 CLKOUT System Clock Output (=CPU Clock) Symbol Pin Type Function |
