This bit is set when the RSTDTS bit is written to one. This will reset the Data Toggle to its initial value for the current Pipe.
This bit is cleared when proceed.
This bit is set when the PFREEZES bit is written to one or when the pipe is not configured or when a STALL handshake has
been received on this Pipe or when an error occurs on the Pipe (PERR is one) or when (INRQ+1) In requests have been
processed or when after a Pipe reset (UPRST.PRSTn rising) or a Pipe Enable (UPRST.PEN rising). This will Freeze the Pipe
requests generation.
This bit is cleared when the PFREEZEC bit is written to one. This will enable the Pipe request generation.
See the UECONn.EPDISHDMA bit description.
For OUT and SETUP Pipe:
This bit is set when the current bank is free, at the same time than TXOUTI or TXSTPI.
This bit is cleared when the FIFOCONC bit is written to one. This will send the FIFO data and switch the bank.
For IN Pipe:
This bit is set when a new IN message is stored in the current bank, at the same time than RXINI.
This bit is cleared when the FIFOCONC bit is written to one. This will free the current bank and switch to the next bank.
This bit is set when the NBUSYBKES bit is written to one.This will enable the Transmitted IN Data interrupt (NBUSYBKE).
This bit is cleared when the NBUSYBKEC bit is written to one. This will disable the Transmitted IN Data interrupt (NBUSYBKE).
This bit is set when the SHORTPACKETES bit is written to one. This will enable the Transmitted IN Data IT
(SHORTPACKETIE).
This bit is cleared when the SHORTPACKETEC bit is written to one. This will disable the Transmitted IN Data IT
(SHORTPACKETE).
