Note: Status bits in this register are latched.
When a channel’s signaling data changes state, the respective bit in registers
The RSCOS bit (RLS4.3) will be set if the channel was also enabled by setting the appropriate bit in RSCSE1:4.
The INTB signal will go low if enabled by the interrupt mask bit RIM4.3. The bit will remain set until read.
