1. These values are based on simulation, with capacitance load between 5pF and 20pF. These values
are not covered by test limits in production.
2. See I/O Pin Characteristics.

4. Where t
SLAVE_IN
is the slave external device input constraint, generally t

5. Where t
MASTER_OUT
is the master external device output response time, generally t
EXT_MOV
+t
LINE_DELAY

6. Where t
MASTER_IN
is the master external device input constraint, generally t
EXT_MIS
+t
LINE_DELAY

.
7. t
LINE_DELAY
is the transmission line time delay.
8. t
EXT_MIS
is the input constraint for the master external device.
9. t
APBC
is the APB period for SERCOM.
10. When the integrity of communication is required to maintain both transmission and reception, the
maximum SPI clock frequency should be the lower value of the reception or transmission mode
maximum frequency as shown in the following equations.
