14.11 COMMUNICATION INTERFACE CHARACTERISTICS
14.11.1 SPI - Serial Peripheral Interface
Subject to general operating conditions for V DD,
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).
Figure 91. SPI Slave Timing Diagram with CPHA=0 3)
Notes:
1. Data based on design simulation and/or characterisation results, not tested in production.
2. When no communication is on-going the data output line of the SPI (MOSI in master mode, MISO in slave mode) has
its alternate function capability released. In this case, the pin status depends on the I/O port configuration.
3. Measurement points are done at CMOS levels: 0.3xVDD and 0.7xVDD.
