Is There a Tutorial on the 8051 Microcontroller?

Every Triscend E5 Configurable System-on-Chip (CSoC) device contains an embedded, accelerated 8051 microcontroller. Technically speaking, the E5 has a superset of the original 8051 functionality.

The web site 8052.com has some excellent on-line tutorials on the 8051 microcontroller, including those on architecture and programming techniques. There is also a tutorial on the Dallas 80C320 microcontroller, which is similar to the microcontroller embedded within every Triscend E5 device.
