... RESET 1998 Jul 30 2 GENERAL DESCRIPTION The PCF8577C is a single chip, silicon gate CMOS circuit designed to drive liquid crystal displays with segments directly segments in a duplex configuration. The two-line I overheads in remote display applications. I minimized in multiple IC applications by automatic address incrementing, hardware subaddressing and display memory switching (direct drive mode) ...

... BANK A. Odd numbered segment byte registers are called BANK There is one slave address for the PCF8577C (see Fig.6). All addressed devices load the second byte into the control register and each device maintains an identical copy of the control byte in the control register at all times (see respectively ...

... C-bus interface 6.5 Direct drive mode The PCF8577C is set to the direct drive mode by loading the MODE control bit with logic 0. In this mode only four bytes are required to store the data for the 32 segment drivers. Setting the BANK bit to logic 0 selects even bytes (BANK A), setting the BANK bit to logic 1 selects odd bytes (BANK B) ...
