Name:

0xF803C114 [0], 0xF803C134 [1], 0xF803C154 [2], 0xF803C174 [3], 0xF803C194 [4], 0xF803C1B4 [5],

Write-only 

For additional Information, see 

0 = No effect.

1 = Kill the last written bank.

0 = No effect.

1 = Set this bit after a packet has been written into the endpoint FIFO for IN data transfers

– This flag is used to generate a Data IN transaction (device to host). 

– Device firmware checks that it can write a data payload in the FIFO, checking that TXRDY_TRER is cleared.

– Transfer to the FIFO is done by writing in the “Buffer Address” register.

– Once the data payload has been transferred to the FIFO, the firmware notifies the UDPHS device setting 

TXRDY_TRER to one.

– UDPHS bus transactions can start.

– TXCOMP is set once the data payload has been sent.

– Data should be written into the endpoint FIFO only after this bit has been cleared.

– Set this bit without writing data to the endpoint FIFO to send a Zero Length Packet.
