The USB Endpoint x IN MAXP Register, shown in Figure 1.59, indicates the maximum packet size (MAXP) of EPx IN
packet. The default values for all EPx IN MAXP are 0 bytes.

The USB Endpoint x IN FIFO Configuration Register, shown in Figure 1.60, is used to select various FIFO configura-
tions. When the double buffer bit is set, the effective buffer size = 2 x BUF_SIZ. Therefore other EP FIFO buffer’s
starting locations have to be 2 x BUF_SIZ apart.
The user should ensure:
• Buffer Starting Location + Buffer Size do not exceed the 3K byte boundary.
• Endpoint buffers do not overlap with each other.
