11 / 160 page ST10F269-T3 11/160 P0L.0 - P0L.7, P0H.0 P0H.1 - P0H.7 100-107, 108, 111-117 I/O Two 8-bit bidirectional I/O ports P0L and P0H, 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. In case of an external bus configuration, PORT0 serves as the address (A) and as the address / data (AD) bus in multiplexed bus modes and as the data (D) bus in demultiplexed bus modes. Demultiplexed bus modes Data Path Width: 8-bit 16-bit P0L.0 – P0L.7: D0 – D7 D0 - D7 P0H.0 – P0H.7 I/O D8 - D15 Multiplexed bus modes Data Path Width: 8-bit 16-bit P0L.0 – P0L.7: AD0 – AD7 AD0 - AD7 P0H.0 – P0H.7 A8 – A15 AD8 - AD15 P1L.0 - P1L.7 P1H.0 - P1H.7 118-125 128-135 I/O Two 8-bit bidirectional I/O ports P1L and P1H, 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. PORT1 is used as the 16-bit address bus (A) in demultiplexed bus modes and also after switching from a demultiplexed bus mode to a multiplexed bus mode. The following PORT1 pins have alternate functions: 132 I P1H.4 CC24IO CAPCOM2: CC24 Capture Input 133 I P1H.5 CC25IO CAPCOM2: CC25 Capture Input 134 I P1H.6 CC26IO CAPCOM2: CC26 Capture Input 135 I P1H.7 CC27IO CAPCOM2: CC27 Capture Input XTAL1 138 I XTAL1 Oscillator amplifier and/or external clock input. XTAL2 137 O XTAL2 Oscillator amplifier circuit output. To clock the device from an external source, drive XTAL1 while leaving XTAL2 unconnected. Minimum and maximum high / low and rise / fall times specified in the AC Characteristics must be observed. RSTIN 140 I Reset Input with Schmitt-Trigger characteristics. A low level at this pin for a specified duration while the oscillator is running resets the ST10F269-T3. An internal pull-up resistor permits power-on reset using only a capacitor connected to VSS. In bidirec- tional reset mode (enabled by setting bit BDRSTEN in SYSCON register), the RSTIN line is pulled low for the duration of the internal reset sequence. RSTOUT 141 O Internal Reset Indication Output. This pin is driven to a low level during hardware, software or watchdog timer reset. RSTOUT remains low until the EINIT (end of ini- tialization) instruction is executed. NMI 142 I Non-Maskable Interrupt Input. A high to low transition at this pin causes the CPU to vector to the NMI trap routine. If bit PWDCFG = ‘0’ in SYSCON register, when the PWRDN (power down) instruction is executed, the NMI pin must be low in order to force the ST10F269-T3 to go into power down mode. If NMI is high and PWDCFG =’0’, when PWRDN is executed, the part will continue to run in normal mode. If not used, pin NMI should be pulled high externally. VAREF 37 - A/D converter reference voltage. VAGND 38 - A/D converter reference ground. RPD 84 - Timing pin for the return from interruptible powerdown mode and synchronous / asynchronous reset selection. Symbol Pin Type Function |
