GENERAL RELEASE SPECIFICATION
UNIVERSAL SERIAL BUS MODULE
REV 1.1
10-21
TXD1F — Endpoint 1/Endpoint 2 Data Transmit Flag
This read only bit is shared by Endpoint 1 and Endpoint 2. It is set after the data
stored in the shared Endpoint 1/Endpoint 2 transmit buffer has been sent and
an ACK handshake packet from the host is received. Once the next set of data
is ready in the transmit buffers, software must clear this ag by writing a logic 1
to the TXD1FR bit. To enable the next data packet transmission, TX1E must
also be set. If TXD1F bit is not cleared, a NAK handshake will be returned in
the next IN transaction.
Reset clears this bit. Writing a logic 0 to TXD1F has no effect.
1 =
Transmit on Endpoint 1 or Endpoint 2 has occurred
0 =
Transmit on Endpoint 1 or Endpoint 2 has not occurred
EOPF — End of Packet Detect Flag
This read only bit is set when a valid End-of-Packet sequence is detected on
the D+ and D- lines. Software must clear this ag by writing a logic 1 to the
EOPFR bit.
Reset clears this bit. Writing a logic 0 to EOPF has no effect.
1 =
End-of-Packet sequence has been detected
0 =
End-of-Packet sequence has not been detected
RESUMF — Resume Flag
This read only bit is set when USB bus activity is detected while the SUSPND
bit is set. Software must clear this ag by writing a logic 1 to the RESUMFR bit.
Reset clears this bit. Writing a logic 0 to RESUMF has no effect.
1 =
USB bus activity has been detected
0 =
No USB bus activity has been detected
RESUMFR — Resume Flag Reset
Writing a logic 1 to this write only bit will clear the RESUMF bit if it is set.
Writing a logic 0 to RESUMFR has no effect. Reset clears this bit.
TXD1IE — Endpoint 1/Endpoint 2 Transmit Interrupt Enable
This read/write bit enables the USB to generate an interrupt when the shared
Transmit Endpoint 1/Endpoint 2 interrupt ag (TXD1F) bit becomes set. Reset
clears this bit.
1 =
USB interrupts enabled for Transmit Endpoints 1 and 2
0 =
USB interrupts disabled for Transmit Endpoints 1 and 2
EOPIE — End of Packet Detect Interrupt Enable
This read/write bit enables the USB to generate an interrupt when the EOPF bit
becomes set. Reset clears this bit.
1 =
USB interrupts enabled for Transmit Endpoints 1 and 2
0 =
USB interrupts disabled for Transmit Endpoint 1 and 2
TXD1FR — Endpoint 1/Endpoint 2 Transmit Flag Reset
Writing a logic 1 to this write only bit will clear the TXD1F bit if it is set. Writing a
logic 0 to TXD1FR has no effect. Reset clears this bit.
