UPINTX - USB Pipe INTerrupt Register for Pipe X

Set UPNUM register to point to the relevant Pipe before using the UPINTX register.

• Bit 7 - FIFOCON : FIFO Control

For OUT and SETUP Pipe:

Set by hardware when the current bank is free, at the same time than TXOUT or TXSTP.

Clear to send the FIFO data. Setting by software has no effect.

For IN Pipe:

Set by hardware when a new IN message is stored in the current bank, at the same time than

RXIN.

Clear to free the current bank and to switch to the following bank. Setting by software has no

effect.

• Bit 6 - NAKEDI : NAK Handshake received

Set by hardware when a NAK has been received on the current bank of the Pipe. This triggers

an interrupt if the NAKEDE bit is set in the UPIENX register.

Shall be clear to handshake the interrupt. Setting by software has no effect.
