Notes: 1. When BRDYM is 0, to clear the status indicated by the bits in this register, write 0 only
to the bits to be cleared; write 1 to the other bits.
2. When BRDYM is 0, clearing this bit should be done before accessing the FIFO.
17.3.19 NRDY Interrupt Status Register (NRDYSTS)
NRDYSTS is a register that indicates the NRDY interrupt status for each pipe.
This register is initialized by a power-on reset.
