ATTCH Interrupt Status 

Indicates the status of the ATTCH interrupt when the 
host controller function is selected.  

0: ATTCH interrupts not generated 

1: ATTCH interrupts generated 

When this module has generated J-state or K-state 
of the full-speed or low-speed level signal for 2.5 

s, 

this module detects the ATTCH interrupt and sets 
this bit to 1. Here, if the corresponding interrupt 
enable bit has been set to 1, this module generates 
the interrupt.  

Specifically, this module detects the ATTCH interrupt 
on any of the following conditions. 

  K-stateSE0, or SE1 changes to J-state, and J-

state continues 2.5 

s. 

  J-state, SE0, or SE1 changes to K-state, and K-

state continues 2.5 

s. 

When the function controller function is selected, the 
read value is invalid.

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