Read/Write

This register can only be written if the WPEN bit is cleared in the 



0: The parallel capture mode is disabled.

1: The parallel capture mode is enabled.





0: The parallel capture mode samples the data when both data enables are active.

1: The parallel capture mode samples the data whatever the data enables are.



Independently from the ALWYS bit:

0: The parallel capture mode samples all the data. 

1: The parallel capture mode samples the data only every other time.



This bit is useful only if the HALFS bit is set to 1. If data are numbered in the order that they are received with an index from 
0 to n:

0: Only data with an even index are sampled.
