R/W Description
R/W*¹ 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
This module detects the ATTCH interrupt on detecting
J-state or K-state of the full-speed or low-speed level
signal for 2.5 µs, and sets this bit to 1. Here, if software
has set the corresponding interrupt enable bit to 1, this
module generates the interrupt.
Specifically, this module detects the ATTCH interrupt
on any of the following conditions.
• K-state, SE0, or SE1 changes to J-state, and J-
state continues 2.5 µs.
• J-state, SE0, or SE1 changes to K-state, and K-
state continues 2.5 µs.
When the function controller function is selected, the
read value is invalid.
R
Reserved
These bits are always read as 0. The write value
should always be 0.
