DcInterrupt register (R: C0H)
This command indicates the sources of interrupts as stored in the 4-byte DcInterrupt
register. Each individual endpoint has its own interrupt bit. The bit allocation of the
DcInterrupt register is shown in
Table 140
. Bit BUSTATUS is used to verify the current
bus status in the interrupt service routine. Interrupts are enabled using the
DcInterruptEnable register, see
Section 16.1.5
.
While reading the DcInterrupt register, it is recommended that both 2-byte words are
read completely.
Code (Hex): C0
read DcInterrupt register
Transaction
read 4 bytes (code or data)

Logic 1 indicates the interrupt source(s): endpoint 14 to 1.
Logic 1 indicates the interrupt source: control IN endpoint.
Logic 1 indicates the interrupt source: control OUT endpoint.
Monitors the current USB bus status (0 = awake, 1 = suspend).
Logic 1 indicates that an EOT interrupt has occurred for a short
period.
