2 / 17 page 2/17 MTV021 Revision 5.0 6/29/1999 MTV021 MYSON TECHNOLOGY 1.0 PIN CONNECTION 2.0 PIN DESCRIPTIONS Name I/O Pin No. Descriptions N16 N20 N24 VSSA - 1 1 1 Analog ground. This ground pin is used to internal analog circuitry. VCO I/O 2 2 2 Voltage Control Oscillator. This pin is used to control the internal oscil- lator frequency by DC voltage input from external low pass filter. RP I/O 3 3 3 Bias Resistor. The bias resistor is used to regulate the appropriate bias current for internal oscillator to resonate at specific dot frequency. VDDA - 4 4 4 Analog power supply. Positive 5 V DC supply for internal analog cir- cuitry. And a 0.1uF decoupling capacitor should be connected across to VDDA and VSSA. HFLB I 5 5 5 Horizontal input. This pin is used to input the horizontal synchronizing signal. It is a leading edge triggered and has an internal pull-up resistor. SSB I 6 6 6 Serial interface enable. It is used to enable the serial data and is also used to select the operation of I2C or SPI bus. If this pin is left floating, I2C bus is enabled, otherwise the SPI bus is enabled. SDA I 7 7 7 Serial data input. The external data transfer through this pin to internal display registers and control registers. It has an internal pull-up resistor. SCK I 8 8 8 Serial clock input. The clock-input pin is used to synchronize the data transfer. It has an internal pull-up resistor. PWM0 O - 9 9 Open-Drain PWM D/A converter 0. The output pulse width is program- mable by the register of Row 15, Column 23. PWM1 O - 10 10 Open-Drain PWM D/A converter 1. The output pulse width is program- mable by the register of Row 15, Column 24. PWM2 O - - 11 Open-Drain PWM D/A converter 2. The output pulse width is program- mable by the register of Row 15, Column 25. PWM3 O - - 12 Open-Drain PWM D/A converter 3. The output pulse width is program- mable by the register of Row 15, Column 26.
