23.2.1 REACM_RCHn — REACM Channel (n) Output Pin a, b and c
Each reaction channel provides three outputs to be connected to device primary output PADs. These
outputs can be configured as necessary in order to meet application requirements. Thus the active state as
well as overall functionality are defined by the registers within the Reaction Module and the defined
sequence of operation. The reset state for these outputs is zero.
23.3 Memory map and register definition
This section provides a detailed description of all Reaction Module registers accessible to the end user.
