12.1.5 Write/Read Interrupt Enable Register
Table 21:
This command is used to individually enable/disable interrupts from all endpoints, as
well as interrupts caused by events on the USB bus (SOF, SOF lost, EOT, suspend,
resume, reset). A bus reset will not change any of the programmed bit values.
The command accesses the Interrupt Enable Register, which consists of 4 bytes. The
bit allocation is given in
Code (Hex): C2/C3 — write/read Interrupt Enable Register
Transaction — write/read 4 bytes

Description
Selects DREQ signal polarity (0 = active LOW, 1 = active
HIGH). Bus reset value: unchanged.
Selects DACK signal polarity (0 = active LOW, 1 = active HIGH).
Bus reset value: unchanged.
Selects EOT signal polarity (0 = active LOW, 1 = active HIGH).
Bus reset value: unchanged.
A logic 1 enables remote wake-up via a LOW level on input CS

Bus reset value: unchanged.
A logic 1 enables powering-off during ‘suspend’ state. Output
SUSPEND is configured as a power switch control signal for
external devices (HIGH during ‘suspend’). This value should
always be initialized to logic 1. Bus reset value: unchanged.
Selects the interrupt signalling mode on output INT (0 = level,
1 = pulsed). In pulsed mode an interrupt produces an 166 ns
pulse. See
Selects INT signal polarity (0 = active LOW, 1 = active HIGH).
