RECEPTION COUNTER REGISTER (CNT0RXR)
Read/Write
Reset Value: 0000 0000 (00h)
This register contains the allocated buffer size for
endpoint 0 reception, setting the maximum
number of bytes the related endpoint can receive
with the next OUT or SETUP transaction. At the
end of a reception, the value of this register is the
max size decremented by the number of bytes re-
ceived (to determine the number of bytes re-
ceived, the software must subtract the content of
this register from the allocated buffer size).
TRANSMISSION COUNTER REGISTER
(CNT0TXR, CNT1TXR, CNT3TXR, CNT4TXR,
CNT5TXR)
Read/Write
Reset Value 0000 0000 (00h)
This register contains the number of bytes to be
transmitted by Endpoint 0, 1, 3, 4 or 5 at the next
IN token addressed to it.
RECEPTION COUNTER REGISTER (CNT2RXR)
Read/Write
Reset Value: 0000 0000 (00h)
This register contains the allocated buffer size for
endpoint 2
reception, setting the maximum
number of bytes the related endpoint can receive
with the next OUT transaction. At the end of a re-
ception, the value of this register is the max size
decremented by the number of bytes received (to
determine the number of bytes received, the soft-
ware must subtract the content of this register from
the allocated buffer size).
TRANSMISSION COUNTER REGISTER
(CNT2TXR)
Read/Write
Reset Value 0000 0000 (00h)
This register contains the number of bytes to be
transmitted by Endpoint 2 at the next IN token ad-
dressed to it.
