GPMI’s sync mode output timing could be controlled by module’s internal register, say HW_GPMI_TIMING2_CE_DELAY,
HW_GPMI_TIMING_PREAMBLE_DELAY, and HW_GPMI_TIMING2_POST_DELAY. This AC timing depends on these
registers’ setting. In the above table, we use CE_DELAY/PRE_DELAY/POST_DELAY representing these settings each.
