15 / 179 page ![]() ST10F273E Pin data 15/179 Table 1. Pin description Symbol Pin Type Function P6.0 - P6.7 1 - 8 I/O 8-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 6 outputs can be configured as push-pull or open drain drivers. The input threshold of Port 6 is selectable (TTL or CMOS). The following Port 6 pins have alternate functions: 1O P6.0 CS0 Chip select 0 output ... ... ... ... ... 5O P6.4 CS4 Chip select 4 output 6 IP6.5 HOLD External master hold request input I/O SCLK1 SSC1: master clock output / slave clock input 7 O P6.6 HLDA Hold acknowledge output I/O MTSR1 SSC1: master-transmitter / slave-receiver O/I 8 OP6.7 BREQ Bus request output I/O MRST1 SSC1: master-receiver / slave-transmitter I/O P8.0 - P8.7 9-16 I/O 8-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 8 outputs can be configured as push-pull or open drain drivers. The input threshold of Port 8 is selectable (TTL or CMOS). The following Port 8 pins have alternate functions: 9 I/O P8.0 CC16IO CAPCOM2: CC16 capture input / compare output O XPWM0 PWM1: channel 0 output ... ... ... ... ... 12 I/O P8.3 CC19IO CAPCOM2: CC19 capture input / compare output O XPWM0 PWM1: channel 3 output 13 I/O P8.4 CC20IO CAPCOM2: CC20 capture input / compare output 14 I/O P8.5 CC21IO CAPCOM2: CC21 capture input / compare output 15 I/O P8.6 CC22IO CAPCOM2: CC22 capture input / compare output I/O RxD1 ASC1: Data input (Asynchronous) or I/O (Synchronous) 16 I/O P8.7 CC23IO CAPCOM2: CC23 capture input / compare output O TxD1 ASC1: Clock / Data output (Asynchronous/Synchronous) |
