2.4.4 SPI timing specifications

Remarks: 1. Please note, that different serial clock frequency ranges for SPI slave and master

modes are given in Table 2-4.

2. Timing diagrams are shown for TI-format only. Other transfer formats can be configured,

however the AC-timing parameters (setup/hold times, delays) remain in principle

unchanged.

3. Not every external SPI device, that is connected to ERTEC 200, requires usage of all

available SPI signals.

(1)

SPI interface configured to slave mode

TA = -40 to +85°C, VDDCore = 1.35 V ~ 1.65 V, VDDIO = 3.0 V ~ 3.6 V
