Always write zeroes to this bit field.
Number of GPMICLK cycles that the CE/ADDR signals are active before a strobe is asserted. A value of
zero is interpreted as 0.
Data bus hold time in GPMICLK cycles. Also the time that the data strobe is de-asserted in a cycle. A value
of zero is interpreted as 256.
Data bus setup time in GPMICLK cycles. Also the time that the data strobe is asserted in a cycle. A value
of zero is interpreted as 256.
Timeout waiting for NAND Ready/Busy. Used in WAIT_FOR_READY mode. This value is the number of
GPMI_CLK cycles multiplied by 4096.
Always write zeroes to this bit field.
