• 7-0 - DAT7:0 -Data Bits

Set by the software to read/write a byte from/to the endpoint FIFO selected by EPNUM.

• 7-0 - BYCT7:0 - Byte Count Bits

Set by the hardware. BYCT7:0 is:

- (for IN endpoint) increased after each writing into the endpoint and decremented after each

byte sent,

- (for OUT endpoint) increased after each byte sent by the host, and decremented after each

byte read by the software.

• 7-5 - Reserved

The value read from these bits is always 0. Do not set these bits.

• 4-0 - EPINT4:0 - Endpoint Interrupts Bits

Set by hardware when an interrupt is triggered by the UEINTX register and if the corresponding

endpoint interrupt enable bit is set.

Cleared by hardware when the interrupt source is served.
