This register indicates endpoint x(x=1 to 4) IN maximum packet size. The default value is 0 byte.
When the endpoint is initialized due to any reason such as that the request for setting the endpoint
(SET_DESCRIPTOR, SET_CONFIGURATION, SET_INTERFACE, etc.) is received from the host
CPU, change the endpoint x IN maximum packet size value by writing in this register. Set a packet
size value specified for every transfer type to be used.
The configuration of USB endpoint x(x=1 to 4) IN MAXP register is shown in Figure 2.8.47.
