All timing parameters are defined for one chip select and are grouped together in one
SMC_REGISTER according to their type.
Table 25-6
• The SMC_SETUP register groups the definition of all setup parameters: NRD_SETUP,
• The SMC_PULSE register groups the definition of all pulse parameters: NRD_PULSE,
• The SMC_CYCLE register groups the definition of all cycle parameters: NRD_CYCLE,
NCS_RD_SETUP, NWE_SETUP, NCS_WR_SETUP
