Note:
SSP timing characteristics
This module provides a programmable length shift register which allows serial
communication with other SSP devices through a 3 or 4 wire interface (SSP_CLK,
SSP_MISO, SSP_MOSI and SSP_CSn). The SSP supports the following features:

The following tables and figures show the characterization of the SSP using the SPI
protocol.
Table 44.
T = Tc(CLK) = SSP_CLK period is equal to the SSP module master clock divided by a
configurable divider.
