2)GPMI’s output timing could be controlled by module’s internal register, say
3)AS minimum value could be 0, while DS/DH minimum value is 1.
Freescale Semiconductor
The Flash clock maximum frequency is 100 MHz.
HW_GPMI_TIMING0_ADDRESS_SETUP,HW_GPMI_TIMING0_DATA_SETUP,HW_GPMI_TIMING0_DATA_HOLD, this AC
timing depends on these registers’ setting. In the above table we use AS/DS/DH representing these settings each.
