ENDPOINTS
E68A 1 EP0BCH Endpoint 0 Byte Count H (BC15) (BC14) (BC13) (BC12) (BC11) (BC10) (BC9) (BC8) xxxxxxxx RW Even though the EP0 buffer is
only 64 bytes, the EP0 byte
count is expanded
to 16-bits to allow using the
Autoptr with a custom length,
instead of USB-
dictated length (from Setup
Data Packet and number of
requested bytes).
The byte count bits in paren-
theses apply only when SD-
PAUTO = 0
