14 / 92 page  PFS172 8bit MTP MCU with 8-bit ADC ©Copyright 2020, PADAUK Technology Co. Ltd Page 14 of 92 PDK-DS-PFS172-EN_V000-May 8, 2020 Pin Name Pin Type & Buffer Type Description PB7 / AD7 / CIN5- / TM3PWM IO ST / CMOS / Analog The functions of this pin can be: (1) Bit 7 of port B. It can be configured as digital input, two-state output with pull-high / pull-low resistor by software independently. (2) Channel 7 of ADC analog input (3) Minus input source 5 of comparator (4) PWM output from Timer3 When this pin is configured as analog input, please use bit 7 of register pbdier to disable the digital input to prevent current leakage. The bit 7 of pbdier register can be set to “0” to disable digital input; wake-up from power-down by toggling this pin is also disabled. PB6 / AD6 / CIN4- / TM3PWM IO ST / CMOS / Analog The functions of this pin can be: (1) Bit 6 of port B. It can be configured as digital input, two-state output with pull-high / pull-low resistor by software independently. (2) Channel 6 of ADC analog input (3) Minus input source 4 of comparator (4) PWM output from Timer3 When this pin is configured as analog input, please use bit 6 of register pbdier to disable the digital input to prevent current leakage. The bit 6 of pbdier register can be set to “0” to disable digital input; wake-up from power-down by toggling this pin is also disabled. PB5 / AD5 / INT0 / TM3PWM IO ST / CMOS / Analog The functions of this pin can be: (1) Bit 5 of port B. It can be configured as digital input, two-state output with pull-high / pull-low resistor by software independently. (2) Channel 5 of ADC analog input (3) External interrupt line 0. It can be used as an external interrupt line 0. Both rising edge and falling edge are accepted to request interrupt service and configurable by register setting. (4) PWM output from Timer3 When this pin is configured as analog input, please use bit 5 of register pbdier to disable the digital input to prevent current leakage. The bit 5 of pbdier register can be set to “0” to disable digital input; wake-up from power-down by toggling this pin is also disabled. PB4 / AD4 / TM2PWM IO ST / CMOS / Analog The functions of this pin can be: (1) Bit 4 of port B. It can be configured as digital input, two-state output with pull-high / pull-low resistor by software independently. (2) Channel 4 of ADC analog input (3) PWM output from Timer2 When this pin is configured as analog input, please use bit 4 of register pbdier to disable the digital input to prevent current leakage. The bit 4 of pbdier register can be set to “0” to disable digital input; wake-up from power-down by toggling this pin is also disabled. |
