NRDY

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.

BRDY

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.
