The 8x931AA and 8x931HA USB peripheral controllers are based on the MCS^®51

microcontroller. They consist of standard 8XC51Fx peripherals plus a USB module. The

8x931HA USB module provides both USB hub and USB embedded function capabilities. The

8x931HA supports USB hub functionality, embedded function, suspend/resume modes,

isochronous/non-isochronous transfers, and is USB rev 1.0 specification compliant. The USB
