[USB Endpoint x (x = 0 to 4) IN Max. Packet Size Register]
IN_MAXP
This register specifies the maximum packet size (MAXP) of an
endpoint x IN packet. The value set for endpoint 1 is the number
of transmitted bytes divided by 8, and the value set for endpoints
0, 2, 3, and 4 is the actual number of transmitted bytes. The CPU
can change these values using the SET_DESCRIPTOR com-
mand.
The initial value for endpoints 0, 2, 3 and 4 is 8, and the initial
value for endpoint 1 is 1.
[USB Endpoint x (x = 0 to 4) OUT Max. Packet Size Register]
OUT_MAXP
This register specifies the maximum packet size (MAXP) of an
Endpoint x OUT packet. The value set for endpoint 1 is the num-
ber of received bytes divided by 8, and the value set for endpoints
0, 2, 3, and 4 is the actual number of received bytes. The CPU
can change these values using the SET_DESCRIPTOR com-
mand.
The initial value for endpoints 0, 2, 3, and 4 is 8, and the initial
value for endpoint 1 is 1. When using the endpoint 0, both USB
endpoint x IN max. packet size register (IN _MAXP) and USB end-
point x OUT max. packet size register (OUT_MAXP) are set to the
same value. Changing one register
’
s value effectively changes the
value of the other register as well.
