LCD Driver
The SA9110A has an on-chip LCD driver capable of driving a 4 backplane, 7 digit
(7 segment) display, as well as 6 announciators.
The backplane repitition frequency is approximately 90Hz.
The most significant digit is addressed by columns S[13] and S[12] and the least
significant digit by S[1] and S[0]. Announciators for the total register, 4 tariff registers
and energy direction indication are available on the 'h' segments of the 6 least
significant digits. The display segments are addressed via the column outputs given
in the table below:
