TP0SIZ3–TP0SIZ0 — Endpoint 0 Transmit Data Packet Size

These read/write bits store the number of transmit data bytes for the

next IN token request for endpoint 0. These bits are cleared by reset.

11.8.6 USB Control Register 1

T1SEQ — Endpoint 1 Transmit Sequence Bit

This read/write bit determines which type of data packet (DATA0 or

DATA1) will be sent during the next IN transaction directed to

endpoint 1. Toggling of this bit must be controlled by software. Reset

clears this bit.

1 = DATA1 token active for next endpoint 1 transmit

0 = DATA0 token active for next endpoint 1 transmit

STALL1 — Endpoint 1 Force Stall Bit

This read/write bit causes endpoint 1 to return a STALL handshake

when polled by either an IN or OUT token by the USB host controller.

Reset clears this bit.

1 = Send STALL handshake

0 = Default

TX1E — Endpoint 1 Transmit Enable

This read/write bit enables a transmit to occur when the USB host

controller sends an IN token to endpoint 1. The appropriate endpoint

enable bit, ENABLE1 bit in the UCR3 register, also should be set.

Software should set the TX1E bit when data is ready to be

transmitted. It must be cleared by software when no more data needs

to be transmitted.
