address range $00 – $1F are directly bit-accessible using the SBI and CBI instructions. In
these registers, the value of single bits can be checked by using the SBIS and SBIC instruc-
tions. Refer to the instruction set documentations of the AVR for more details. When using the
I/O specific commands, IN and OUT, the I/O address $00 – $3F must be used. When address-
ing I/O registers as SRAM, $20 must be added to this address. All I/O register addresses
throughout this document are shown with the SRAM address in parentheses.
For compatibility with future devices, reserved bits should be written to zero if accessed.
Reserved I/O memory addresses should never be written.
USB Hub
A block diagram of the USB hardware of the AT43USB353M is shown in Figure 3. The USB
hub of the AT43USB353M has 3 downstream ports. The embedded function is permanently
attached to Port 1. Ports 2 and 3 are available as external ports. The actual number of ports
used is strictly defined by the firmware of the AT43USB353M and can vary from 0 to 2.
Because the exact configuration is defined by firmware, ports 2 and 3 may even function as
permanently attached ports as long as the Hub Descriptor identifies them as such.
USB Function
The embedded USB function has its own device address and has a default end-point plus 3
other programmable end-points. Two of these end-points contain their own 64-byte FIFO while
the third end-point has an 8-byte FIFO. End-points 1 - 3 can be programmed as interrupt IN or
OUT or bulk IN or OUT end-points.
