ADDRESSING
Data is downloaded in bytes into the RAM matrix of the PCF8812 as indicated in Figs.3, 4, 5 and 6. The display RAM
has a matrix of 65
×
102 bits. The columns are addressed by the address pointer. The address ranges are: X0 to X101
(1100101) and Y0 to Y8 (1000). Addresses outside of these ranges are not allowed. In vertical addressing mode (V = 1)
the Y address increments after each byte (see Fig.6). After the last Y address (Y = 8) Y wraps around to 0 and X
increments to address the next column. In horizontal addressing mode (V = 0) the X address increments after each byte
(see Fig.5). After the last X address (X = 101) X wraps around to 0 and Y increments to address the next row. After the
very last address (X = 101 and Y = 8) the address pointers wrap around to address (X = 0 and Y = 0).
