2 Registers
How to Read Register Tables
Bit Numbers :
Each register is connected with an internal bus of 16-bit wide, so the bit numbers of the
registers located at odd addresses are b15-b8, and those at even addresses are b7-b0.
State of Register at Reset :
Represents the initial state of each register immediately after reset with hexadecimal numbers.
The "H/W reset" is the reset by an external reset signal; the "S/W reset" is the reset by the
USBE bit of the USB Operation Enable Register.
At Read:
... Read enabled
? ... Read disabled (Read value invalid)
0 ... Read always as 0
1 ... Read always as 1
At Write:
... Write enabled
... Write enable conditionally (includes some conditions at write)
— ... Write disabled (Don’t care “0” and “1” at write)
X Write disabled
