0x400E0F50 (PIOA), 0x400E1150 (PIOB), 0x400E1350 (PIOC)

Read/Write

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

.

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.
1: Only data with an odd index are sampled.
