USB Registers
The following sections describe the registers of the AT43USB351M’s function unit.
Reading a bit for which the microcontroller does not have read access will yield a zero value
result. Writing to a bit for which the microcontroller does not have write access has no effect.
Hub Address Register
– HADDR
This register is an artifact of the AT43USB355. It is included in the AT43USB351M to make
the two devices binary-compatible. In the AT43USB351M only bit 7 is meaningful.
Hub Address Register – HADDR
Bit 7 – SAEN: Single Address Enable
In the AT43USB351M, this bit should be set to “1”.
Bit 6..0 – HADD6...0: Hub Address[6:0]
These bits are don’t cares in the AT43USB351M.
