This field defines the delay from NPCS inactive to the activation of another NPCS. The DLYBCS time guarantees non-over-
lapping chip selects and solves bus contentions in case of peripherals having long data float times.
If DLYBCS is less than or equal to six, six MCK periods (or 6*N MCK periods if FDIV is set) will be inserted by default.
Otherwise, the following equation determines the delay:
If FDIV is 0:
If FDIV is 1:

PCS: Peripheral Chip Select
DLYBCS: Delay Between Chip Selects
PCS = xxx0
PCS = xx01
PCS = x011
PCS = 0111
PCS = 1111
(x = don’t care)
NPCS[3:0] output signals = PCS.
Delay Between Chip Selects
Delay Between Chip Selects
NPCS[3:0] = 1110

NPCS[3:0] = 1011
NPCS[3:0] = 0111
