Read:
Write:
These read/write bits store the number of transmit data bytes for the
next IN token request for embedded device Endpoint 0. These bits
are cleared by reset.
This read/write bit determines which type of data packet (DATA0 or
DATA1) will be sent during the next IN transaction directed to
embedded device Endpoint 1 or 2. Toggling of this bit must be
controlled by software. Reset clears this bit.
This read/write bit specifies whether the data inside the registers
DE1D0-DE1D7 are used for embedded device Endpoint 1 or 2. If all
the conditions for a successful Endpoint 2 USB response to a host’s
IN token are satisfied (TXD1F=0, TX1E=1, DSTALL2=0, and
ENABLE2=1) except that the ENDADD bit is configured for
Endpoint 1, the USB responds with a NAK handshake packet. Reset
clears this bit.
1 = DATA1 Token active for next embedded device Endpoint 1/2
0 = DATA0 Token active for next embedded device Endpoint 1/2
