2 S1D13704/5 Bus Interface

This section is summary of the bus interface modes available on the S1D13704 and S1D13705 LCDCs, and offers some detail on the Generic #2 bus mode used to implement the interface to the TMPR3912/22U.

2.1 Bus Interface Modes

The S1D13704/5 implements a general-purpose 16-bit interface to the host microprocessor, which may operate in one of several modes compatible with most of the popular embedded microprocessor families.

Bus interface mode selections are made during reset by sampling the state of the configu- ration pins CNF[2:0] and the BS# line. Table 5-1 in the S1D13704 or S1D13705 Hardware Functional Specification details the values needed for the configuration pins and BS# to select the desired mode.
