19.12 Communication interface characteristics
19.12.1
SPI - serial peripheral interface
Subject to general operating conditions for VDD, fOSC, and TA unless otherwise specified.
Refer to I/O port characteristics for more details on the input/output alternate function
characteristics (SS, SCK, MOSI, MISO).

1. Data based on design simulation and/or characterization results, not tested in production.
2. Depends on fCPU. For example, if fCPU = 8 MHz, then TCPU = 1 / fCPU = 125ns and tsu(SS) = 550ns.
