depending on the IO-configuration code, written and stored in the slave device.
The timing of the data transfer is presented in Figure 4.
Strobe signal PSTBn flags and governs the data transfer as follows:
a)
parameter port is set ‘output’:
output data become valid upon the HL-edge of the strobe and will remain so until the next HL-edge, hence during the entire
strobe cycle;
b) parameter port is set ‘input’:
input data to be valid within a specific time window relative to the HL-edge of the strobe, after completion of the strobe’s L-
phase.
Output data as per a) could be easily latched with the LH-edge of strobe PSTBn, if at all necessary.
