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

Register Description:
Receive Signaling Change Of State Information
Register Address:
38h, 39h, 3Ah, 3Bh

RSINFO4
When a channel’s signaling data changes state, the respective bit in registers RSINFO1-4 will be set. If the channel was also
enabled as an interrupt source by setting the appropriate bit in RSCSE1–4, an interrupt is generated. The bit will remain set
until read.
