Data Sampling
•Read is controlled by NCS (MODE.READMODE = 0)
Figure 18-10 on page 315
shows the typical read cycle of an LCD module. The read data is valid
t
after the falling edge of the NCS signal and remains valid until the rising edge of NCS. Data
PACC
must be sampled when NCS is raised. In that case, the MODE.READMODE bit must be written
to zero (read is controlled by NCS): the SMC internally samples the data on the rising edge of
CML_SMC that generates the rising edge of NCS, whatever the programmed waveform of NRD
may be.
