PID Select (Bits [7:4])
The PID Select field is defined in
tokens are automatically sent based on settings in the Host n
Control Register and do not need to be written in this register.
Table 34.PID Select Definition
Host n Count Result Register [R]
Register Description
The Host n Count Result Register is a read-only register that
contains the size difference in bytes between the Host Count
Value specified in the Host n Count Register and the last
packet received. If an overflow or underflow condition occurs,
that is the received packet length differs from the value
specified in the Host n Count Register, the Length Exception
Flag bit in the Host n Endpoint Status Register will be set. The
value in this register is only value when the Length Exception
Flag bit is set and the Error Flag bit is not set, both bits are in
the Host n Endpoint Status Register.

Endpoint Select (Bits [3:0])
The Endpoint field allows addressing of up to 16 different
endpoints.
Reserved
All reserved bits should be written as ‘0’.
Result (Bits [15:0])
The Result field contains the differences in bytes between the
received packet and the value specified in the Host n Count
Register. If an overflow condition occurs, Result [15:10] will be
set to ‘111111’, a 2’s complement value indicating the
additional byte count of the received packet. If an underflow
condition occurs, Result [15:0] indicates the excess bytes
count (number of bytes not used).
Reserved
All reserved bits should be written as ‘0’.
