... Philips Semiconductors LCD direct/duplex driver with 2 I 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) ...

... Philips Semiconductors LCD direct/duplex driver with 2 I C-bus interface 6.10 Display memory mapping The mapping between the eight segment registers and the segment outputs S1 to S32 is given in Tables 1 and 2. Since only one register bit per segment is needed in the direct drive mode, the BANK bit allows swapping of display information. If BANK is set to logic 0 even bytes (BANK A) are displayed ...
