• 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.
