11.9.3
Delay settings
shows the values for the delay after transfer (t
DT
) and CS to SCK delay (t
CSC
) that can be
generated based on the prescaler values and the scaler values set in the DSPI
x
_CTARs. The values
calculated assume a 100 MHz system frequency.
11.9.4
Calculation of FIFO pointer addresses
The user has complete visibility of the TX and RX FIFO contents through the FIFO registers, and valid
entries can be identified through a memory-mapped pointer and a memory-mapped counter for each FIFO.
The pointer to the first-in entry in each FIFO is memory-mapped. For the TX FIFO the first-in pointer is
the transmit next pointer (TXNXTPTR). For the RX FIFO the first-in pointer is the pop next pointer
(POPNXTPTR).
