6.4.1.1 JOG Requirements
The jog feature is optional and is controlled by the Table 328, “SGPIO Output Data
Select Register[0:7] x - SGODSR[0:7]x” on page 484 . When enabled, this feature
monitors the input signal and if the input signal is detected low for about four seconds
it will be forced high for a 250 ms duration.
6.4.1.2 Protocol Engine Pre-Conditioning Requirements
All the Protocol Engine activity and status signals are pre-conditioned when entering
the SGPIO units. The pre-conditioning logic monitors for any short pulse or any high
frequency input signal and ensures that the input signal is stretched and held high for
at least 125 ms.
