DESCRIPTION
I2C-bus serial clock input
LCD row driver data outputs
LCD column driver data outputs
LCD row driver data outputs
test pad output, must be left unconnected (not user accessible)
I2C-bus serial data input/output
ground
test pad input, must be connected to VSS (not user accessible)
negative supply voltage input
the LSB bit of the I2C-bus slave address input is set by connecting this pin to either
0 (VSS) or 1 (VDD)
test pad input, must be connected to VDD (not user accessible)
when the on-chip oscillator is used this pin must be connected to VDD; an external clock
signal, if used, is input at this pin
positive supply voltage
