Setting any of the CH1–CH30 bits in the RSCSE1–RSCSE4 registers causes an interrupt when that channel’s
signaling data changes state.

Register Address:
CH8
CH16
CH24
When a channel’s signaling data changes state, the respective bit in registers RSINFO1–4 is set. An interrupt is
generated if the channel was also enabled as an interrupt source by setting the appropriate bit in RSCSE1–4. The
bit remains set until read.
