Electrical Characteristics
4.3.9
This section provides electrical parametrics and timings for EMI module.
4.3.9.1
The NFC supports normal timing mode, using two flash clock cycles for one access of RE and WE. AC
timings are provided as multiplications of the clock cycle and fixed delay.

The user or board designer must take into account that the use of a frequency other than 26 MHz would require adjustment to
the DPTC–DVFS table, which is incorporated into operating system code.
The PLL reference frequency must be ≤ 35 MHz. Therefore, for frequencies between 35 MHz and 70 MHz, program the
predivider to divide by 2 or more. If the CKIH frequency is above 70 MHz, program the predivider to 3 or more. For PD bit
description, see the reference manual.
