than 15 ms. It is, however, recommended
to keep the resume signaling for
approximately 10 ms. Notice that the
device must report back to the USB host
that it supports Remote Wakeup when the
host sends the GET_STATUS Standard
Device Request.

USB Registers
This section describes all USB registers
used for control and status for the USB.
The USB registers reside in XDATA
memory space in the region 0xDE00-
0xDE3F. These registers can be divided
into three groups: The Common USB
Registers, The Indexed Endpoint
Registers and the Endpoint FIFO
Registers. Overview of Common USB
Registers. Table 51, Table 52 and Table
53 give an overview of register addresses
for each of the three groups respectively
while the remaining tables in this section
describe each register. The Indexed
Endpoint Registers represent the currently
selected endpoint. The USBINDEX register
is used to select the endpoint.
Notice that the upper register addresses
0xDE2C – 0xDE3F are reserved.

Selects current endpoint. Make sure this register has the value of the endpoint before any
of the registers in Table 52 are accessed.
This register must be set to a value in the range 0 – 5.
