BRDY interrupt enabled bit of each pipe (PIPEBRDYE)
When the controller detects the BRDY interrupt for the pipe for which the software has written "1" in this bit, it sets "1"
to the BRDYSTS register PIPEBRDY bit and to the INTSTS0 register BRDY bit, and asserts an interrupt from the
INT_N pin.
When at least one bit from the BRDYSTS register PIPEBRDY bit sets "1", if the software modifies the register interrupt
enabled bit from "0" to "1", the controller asserts an interrupt from the INT_N pin.
NRDY interrupt enabled bit of each pipe (PIPENRDYE)
When the controller detects the NRDY interrupt for the pipe for which the software has written "1" to this bit, it sets "1"
to the NRDYSTS register PIPEBRDY bit and to the INTSTS0 register NRDY bit, and asserts an interrupt from the
INT_N pin.
When at least one bit from the NRDYSTS register PIPENRDY bit sets "1", if the software modifies the interrupt enabled
bit of the register from "0" to "1", the controller asserts an interrupt from the INT_N pin.
