6 / 138 page  ST7L15, ST7L19 6/138 Notes: 1. This pin cannot be configured as external interrupt in ROM devices. 2. OSC1 and OSC2 are not multiplexed in ROM devices and Port C is not present. 3. PCOR not implemented but p-transistor always active in output mode (refer to Figure 29 on page 45) 4PB0/AIN0/SS I/O CT X ei3 XX X Port B0 ADC Analog Input 0 or SPI Slave Select (active low) Caution: No negative current injec- tion allowed on this pin. 5 PB1/AIN1/SCK I/O CT X XX X Port B1 ADC Analog Input 1 or SPI Serial Clock 6 PB2/AIN2/MISO I/O CT X XX X Port B2 ADC Analog Input 2 or SPI Master In/ Slave Out Data 7 PB3/AIN3/MOSI I/O CT X ei2 XX X Port B3 ADC Analog Input 3 or SPI Master Out / Slave In Data 81) PB4/AIN4/CLKIN/ COMPIN- I/O CT X XX X Port B4 ADC Analog Input 4 or External clock input 91) PB5/AIN5 I/O CT X XX X Port B5 ADC Analog Input 5 101) PB6/AIN6 I/O CT X XX X Port B6 ADC Analog Input 6 111) PA7 I/O CT HS X ei1 X X Port A7 12 PA6 /MCO/ ICCCLK/BREAK I/O CT X ei1 XX Port A6 Main Clock Output or In-Circuit Communication Clock or External BREAK Caution: During normal operation this pin must be pulled- up, internal- ly or externally (external pull-up of 10k mandatory in noisy environ- ment). This is to avoid entering ICC mode unexpectedly during a reset. In the application, even if the pin is configured as output, any reset puts it back in input pull-up 13 PA5 /ICCDATA/ ATPWM3 I/O CT HS X ei1 XX Port A5 In-Circuit Communication Data or Autoreload Timer PWM3 14 PA4/ATPWM2 I/O CT HS X XX Port A4 Autoreload Timer PWM2 15 PA3/ATPWM1 I/O CT HS X ei0 XX Port A3 Autoreload Timer PWM1 16 PA2/ATPWM0 I/O CT HS X XX Port A2 Autoreload Timer PWM0 17 PA1/ATIC I/O CT HS X XX Port A1 Autoreload Timer Input Capture 181) PA0/LTIC I/O CT HS X XX Port A0 Lite Timer Input Capture 192) OSC2/PC1 I/O X X Port C13) Resonator oscillator inverter output 202) OSC1/CLKIN/PC0 I/O X X Port C03) Resonator oscillator inverter input or External clock input Pin No. Pin Name Level Port / Control Main Function (after reset) Alternate Function SO20 Input Output 1 |
