PDT
[0:1]
Delay after transfer prescaler. The PDT field selects the prescaler value for the delay between the negation of the
PCSx signal at the end of a frame and the assertion of PCSx at the beginning of the next frame. The PDT field is
only used in master mode. The following table lists the prescaler values. The description for bitfield DT in Ta ble 2 0- 5
details how to compute the delay after transfer.
14–15
PBR
[0:1]
Baud rate prescaler. Selects the prescaler value for the baud rate. Use in master mode only. The baud rate is the
frequency of the serial communications clock (SCKx). The system clock is divided by the prescaler value before the
baud rate selection takes place. The baud rate prescaler values are listed in the following table. The description for
PBR in Section 20.4.6.1, “Baud Rate Generator” details how to compute the baud rate.
