DESCRIPTION

O Open-drain, active LOW output which allows selective

contrast reduction of the TV picture to enhance a

mixed mode display.

− +3.3 V analog power supply

O Pixel rate output of the BLUE colour information.

O Pixel rate output of the GREEN colour information.

O Pixel rate output of the RED colour information.

O Video/data switch push-pull output for dot rate fast

blanking.

I Schmitt triggered input TTL version of the horizontal

sync pulse. The polarity of this pulse is programmable

by register bit TXT1.H POLARITY.

I Schmitt triggered input for a TTL version of the vertical

sync pulse. The polarity of this pulse is programmable

by register bit TXT1.V POLARITY.

− periphery ground

− +3.3 V core power supply

− crystal oscillator ground

I 12 MHz crystal oscillator input

O 12 MHz crystal oscillator output

I If the reset input is HIGH for at least 2 machine cycles

(24 oscillator periods) while the oscillator is running,

the device is reset. This pin should be connected to

VDDP via a capacitor.

− +3.3 V periphery power supply

I/O Port 1. 8-bit programmable bidirectional port with

I/O alternative functions.

I/O P1.0/INT1 is external interrupt 1 which can be

I/O triggered on the rising and falling edge of the pulse.

I/O

P1.1/T0 is the Counter/Timer 0. P1.2/INT0 is external

interrupt 0. P1.3/T1 is the Counter/Timer 1.

I/O P1.6/SCL0 is the serial clock input for the I2C-bus and

I/O P1.7/SDA0 is the serial data port for the I2C-bus.

I/O P1.4/SCL1 is the serial clock input for the I2C-bus and

P1.5/SDA1 is the serial data port for the I2C-bus.

I OTP programming voltage

− not connected
