USB Endpoint x OUT FIFO configuration Register (x = 1 to 4)
USB Endpoint x IN FIFO Data Registers (x = 0 to 4)
The USB Endpoint x OUT FIFO Configuration Register, shown in Figure 1.64, is used to select various FIFO configura-
tions. When 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.
The USB Endpoint x IN FIFO Data Registers, shown in Figure 1.65 are the USB IN (transmit) FIFO data registers. The
CPU writes data to these registers for the respective Endpoint IN FIFO.
