• 7-3 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 2-0 - PBYCT10:8 - Byte count (high) Bits
Set by hardware. This field is the MSB of the byte count of the FIFO endpoint. The LSB part is
provided by the UPBCLX register.
• 7-0 - PBYCT7:0 - Byte Count (low) Bits
Set by the hardware. PBYCT10:0 is:
- (for OUT Pipe) increased after each writing into the Pipe and decremented after each byte
sent,
- (for IN Pipe) increased after each byte received by the host, and decremented after each byte
read by the software.
• 7 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 6-0 - PINT6:0 - Pipe Interrupts Bits
Set by hardware when an interrupt is triggered by the UPINTX register and if the corresponding
endpoint interrupt enable bit is set.
Cleared by hardware when the interrupt source is served.
