Figure 18-13. WRITEMODE = 1. The Write Operation Is Controlled by NWE
•Write is controlled by NCS (MODE.WRITEMODE = 0)
Figure 18-14 on page 320 shows the waveforms of a write operation with MODE.WRITEMODE
written to zero. The data is put on the bus during the pulse and hold steps of the NCS signal.
The internal data buffers are turned out after the NCSWRSETUP time, and until the end of the
write cycle, regardless of the programmed waveform on NWE.
