Electrical SpecificationQSPI Timings, Master and Slave Mode
2) The PLL jitter is not included. It should be considered additionally, corresponding to the used baudrate. The duty cycle can
be adjusted using the bit fields ECONz.A, B and C with the finest granularity of T_MAX = 1 / f_MAX.
3) Positive deviation lenghtens the high time and shortens the low time of a clock period. Negative deviation does the
opposite.
4) For compensation of the average on-chip delay the QSPI module provides the bit fields ECONz.A, B and C.
5) The setup and hold times are valid for both settings of the input pads thresholds: TTL and AL.

1) Documented value is valid for master transmit or slave receive only. For full duplex the external SPI counterpart timing has
to be taken into account.

be adjusted using the bit fields ECONz.A, B and C with the finest granularity of T_MAX = 1 / f_MAX.
