Table 33: Overview of I2S Registers
11.2.3.6 USB Registers
Registers (Table 36). Each register is
described in detail in Section 13.16.11, starting
on Page 179. Notice that the upper register
addresses 0xDE2C – 0xDE3F are reserved.
The USB registers are all related to USB
configuration and control. The USB registers
can only be accessed through XDATA
memory space and reside in address range
0xDE00 - 0xDE3F. These registers can be
divided into three groups: The Common USB
Registers (Table 34), The Indexed Endpoint
Registers (Table 35), and the Endpoint FIFO
Note: All USB registers lose data in PM2
and PM3, meaning that these power
modes cannot be used on the CC2511Fx
