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.
10 to 7 All 0 R Reserved
These bits are always read as 0. The write value
should always be 0.
