NAND Flash Controller Timing Engine
When the NFC Command register is written, the NFC issues a NAND Flash Command and
optionally performs a data transfer between the NFC SRAM and the NAND Flash device. The
NAND Flash Controller Timing Engine guarantees valid NAND Flash timings, depending on the
set of parameters decoded from the address bus. These timings are defined in the
SMC_TIMINGS register.
For information on the timing used depending on the command, see
Figure 25-36. NAND Flash Controller Timing Engine
