Preliminary Specifications REV. E
Specifications in this manual are tentative and subject to change
Universal Serial Bus
2.18.4.18 USB Endpoint x OUT MAXP Register
The USB Endpoint x OUT MAXP Register, shown in Figure 1.50, indicates the maximum packet size (MAXP)
of an Endpoint x OUT packet. The default values for endpoints 1-4 are 0 bytes. The setting of this register also
affects the configuration of single/dual packet operation. When MAXP > 1/2 of the FIFO size, single packet is
set. When MAXP <= 1/2 of the FIFO size, dual packet mode is set.
Figure 1.50: USB Endpoint x OUT MAXP
2.18.4.19 USB Endpoint x OUT WRT CNT Register
The USB Endpoint x OUT WRT CNT Register, shown in Figure 1.51, contains the number of bytes of the cur-
rent data set in the OUT FIFO. The USB FCU sets the value in the Write Count Register after having success-
fully received a packet of data from the host. The CPU reads the register to determine the number of bytes to
be read from the FIFO.

2.18.4.20 USB Endpoint x FIFO Register
The USB Endpoint x FIFO Register, shown in Figure 1.52 is the USB IN (transmit) and OUT (receive) FIFO
data register. The CPU writes data to this register for the corresponding Endpoint IN FIFO and reads data from
this register for the corresponding Endpoint OUT FIFO.
