Description

The processor interface TLC34075 is controlled via read and write strobes (RD, WR), four register select pins(RS<0:3>), and the 8/6 select pin. The 8/6 select pin is used to select between 8- or 6-bit operation and isprovided in order to maintain compatibility with the IMSG176/8 color palette. This operation is carried outin order to utilize the maximum range of the DACs.

The internal register map of TLC34075 is shown in Table 1. The MPU interface operates asynchronously, with datatransfers being synchronized by internal logic. All the register locations support read and write operations.
