2 SED1374/75 Bus Interface
This section is summary of the bus interface modes available on the SED1374 and
SED1375 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 SED1374/75 implements a general-purpose 16-bit interface to the host micropro-
cessor, 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 SED1374 or SED1375 Hardware
Functional Specification details the values needed for the configuration pins and BS# to
select the desired mode.
