Setup Transaction Normal Response Interrupt Status 

Indicates the status of the setup transaction normal 
response interrupt when the host controller function 
is selected. 

0: SACK interrupts not generated 

1: SACK interrupts generated 

This module detects the SACK interrupt when ACK 
response is returned from the peripheral device 
during the setup transactions issued by this module, 
and sets this bit to 1. Here, if the corresponding 
interrupt enable bit has been set to 1, this module 
generates the SACK interrupt.

R 

Reserved 

These bits are always read as 0. The write value 
should always be 0. 

Notes:  1.  Only 0 can be written. 

 

2.  This module can detect a change in the status indicated by the BCHG bit even while the 

clock supply is stopped (while SCKE is 0), and outputs an interrupt when the 
corresponding interrupt enable bit is enabled. Clearing the status should be done after 
enabling the clock supply.  
No interrupts other than BCHG can be detected while the clock supply is stopped (while 
SCKE is 0). 

 

BRDYSTS is a register that indicates the BRDY interrupt status for each pipe. 

This register is initialized by a power-on reset.
