Address:
EOPIE — End-of-Packet Detect Interrupt Enable
SUSPND — USB Suspend Bit
TXD2IE — Endpoint 2 Transmit Interrupt Enable
Reset:
Read:
Write:
This read/write bit enables the USB to generate CPU interrupt
requests when the EOPF bit becomes set. Reset clears the EOPIE
bit.
To save power, this read/write bit should be set by the software if a
3ms constant idle state is detected on the USB bus. Setting this bit
puts the transceiver into a power-saving mode. The RESUMF flag
must be cleared before setting SUSPND. Software must clear this bit
after the resume flag (RESUMF) is set while this resume interrupt flag
is serviced.
This read/write bit enables the transmit endpoint 2 to generate CPU
interrupt requests when the TXD2F bit becomes set. Reset clears the
TXD2IE bit.
