These pins drive the LEDs.ROW24/COM15~ROW31/COM8ODrive LED outputs or common outputs. Each COM pin is double bonded.COM0~COM7 O Common outputs. Each COM pin is double bonded.SYNCOSCI/OI/OIf the RC Master Mode or EXT CLK Master Mode command is programmed, the synchronoussignal is output to SYN pin.If the Slave Mode command is programmed, the synchronous signal is input from SYN pin.If the RC Master Mode command is programmed, the system clock source is from on-chipRC oscillator and system clock is output to OSC pin.If the Slave Mode or EXT CLK Master Mode command is programmed, the system clocksource is input from external clock via the OSC pin.DATA I/O Serial data input or output with pull-high resistorWRRDCSIIIWRITE clock input with pull-high resistor Data on the DATA lines are latched into theHT1632C on the rising edge of the WR signal.READ clock input with pull-high resistor. The HT1632C RAM data is clocked out on thefalling edge of the RD signal. The clocked out data will appear on the DATA line. The hostcontroller can use the next rising edge to latch the clocked out data.Chip select input with pull-high resistor When the CS line is high, the data and commandread from or written to the HT1632C is disabled, and the serial interface circuit is also reset.If CS is low, the data and command transmission between the host controller and theHT1632C are all enabled.LED_VDD Positive power supply for driver circuit. Each LED_VDD pin is double bonded.LED_VSS Negative power supply for driver circuit, ground. Each LED_VSS pin is double bonded.VSS Negative power supply for logic circuit, ground.VDD Positive power supply for logic circuit.Rev. 1.20 2 June 28, 2011
