5 / 27 page SPMC802B 4. SIGNAL DESCRIPTIONS 4.1. PIN Descriptions (32 PIN) Mnemonic PIN No. Functional Description VDD 28 System Power Supply. VSS 27 System Ground. XO/R 4 Crystal In or Resistor In Input. An external resistive pull-up is used to connect with internal OSC circuitry for generating the internal clock and the related time base in R-Oscillation mode. It will be connected with external crystal for a crystal oscillation circuitry in crystal mode. XI 5 Crystal Output or External Clock Input. External clock input is used to connect with internal clock circuitry to generate the internal clock and the related time base in External clock mode. It will be connected with external crystal for a crystal oscillation circuitry in crystal mode. PA7:0 9, 10, 11, 12 20, 21, 22, 23 GPIO Port A7:0. General-purpose inputs/outputs. Using the internal setting can configure it. In addition, PA7 can be used as the external interrupt input. PA5:4 can be the compare inputs of Comparator. PA3:0 can be the group input of external interrupt. PB5 (Vpp) 24 GPIO Port B5. General-purpose input/output. Using the internal setting can configure it. In addition, PB5 can be used as the external Main IRQ input. It is used as Programming Voltage input in Programming mode. PB1 (SCK) 29 GPIO Port B1. General-purpose input/output.
