ACSS
The SMC can be configured to work with an external liquid crystal display (LCD) controller by
setting the ACSS (Address to Chip Select Setup) bit in the SMC_CSR registers
Select Registers” on page
In LCD mode, NCS is shortened by one/two/three clock cycles at the leading and trailing edges,
providing positive address setup and hold. For read accesses, the data is latched in the SMC
when NCS is raised at the end of the access.
Additionally, WSEN must be set and NWS programmed with a value of two or more superior to
ACSS. In LCD mode, it is not recommended to use RWHOLD or RWSETUP. If the above condi-
tions are not satisfied, SMC does not operate correctly.
