Bit Bit Name
Initial
Value R/W Description
9 NRDY 0 R Buffer Not Ready Interrupt Status
0: NRDY interrupts not generated
1: NRDY interrupts generated
This module sets this bit to 1 when at least one
PIPENRDY bit in NRDYSTS is set to 1 among the
PIPENRDY bits corresponding to the PIPENRDYE
bits in NRDYENB to which 1 has been set (when this
module detects the NRDY interrupt status in at least
one pipe among the pipes for which the NRDY
interrupt output is enabled).
For the conditions for PIPENRDY status assertion,
refer to section 26.4.2 (2), NRDY Interrupt.
This module clears this bit to 0 when 0 is written to
all the PIPENRDY bits corresponding to the
PIPENRDYE bits to which 1 has been set.
This bit cannot be cleared to 0 even if 0 is written to
this bit.
8 BRDY 0 R Buffer Ready Interrupt Status
Indicates the BRDY interrupt status.
0: BRDY interrupts not generated
1: BRDY interrupts generated
This module sets this bit to 1 when at least one
PIPEBRDY bit in BRDYSTS is set to 1 among the
PIPEBRDY bits corresponding to the PIPEBRDYE
bits in BRDYENB to which 1 has been set (when this
module detects the BRDY interrupt status in at least
one pipe among the pipes for which the BRDY
interrupt output is enabled).
For the conditions for PIPEBRDY status assertion,
refer to section 26.4.2 (1), BRDY Interrupt.
This module clears this bit to 0 when 0 is written to
all the PIPEBRDY bits corresponding to the
PIPEBRDYE bits to which 1 has been set.
This bit cannot be cleared to 0 even if 0 is written to
this bit.
