This section describes the DC and AC electrical specifications for the SPI of the MPC8313E

17.1 SPI DC Electrical Characteristics

Table 58 provides the DC electrical characteristics for the MPC8313E SPI.

Notes:

1. Input specifications are measured from the 50% level of the signal to the 50% level of the rising edge

of SYS_CLK_IN. Timings are measured at the pin.

2. IPIC inputs and outputs are asynchronous to any visible clock. IPIC outputs should be synchronized

before use by any external synchronous logic. IPIC inputs are required to be valid for at least tPIWID ns

to ensure proper operation when working in edge triggered mode.
