The dump contains the **token table** of a BASIC interpreter for an 8051/80535 family system (likely a monitor BASIC stored in ROM). The bytes `80h–FFh` are BASIC token codes mapped to command/function names. I extracted the commands and functions below.

## Hardware-specific 8051/80535 commands

These are not standard Microsoft BASIC commands; they are extensions for the Siemens/Intel 80535 peripherals:

* `PWM` – pulse width modulation output
* `PH0`, `PH1` – phase outputs (probably PWM phase control)
* `BAUD` – serial baud rate setting
* `CLOCK` – system clock configuration
* `XTAL` – crystal frequency
* `TIMER0`, `TIMER1`, `TIMER2` – timer registers
* `TCON`, `T2CON`, `TMOD` – 8051 timer control registers
* `PORT1`, `PORT4`, `PORT5` – I/O ports
* `PCON` – power control register
* `IE`, `IP` – interrupt enable/priority registers
* `ADC`, `ADCON`, `ADDAT`, `DAPR` – analog converter control

---

## A small example program in this BASIC might look like:

```
10 BAUD 9600
20 PORT1 = 255
30 FOR I=0 TO 100 STEP 1
40   PWM 50
50 NEXT I
60 END
```

---

The token table strongly suggests this is **not a generic 8051 BASIC**, but a **microcontroller control BASIC** designed for an 80535 development board (possibly PHYTEC, based on your previous MCB-51 monitor question). The commands `PORT4`, `PORT5`, `ADC`, `PWM`, `TIMER2`, `CC1-CC3` are typical of the Siemens SAB80C535 peripheral set.

I can also reconstruct the **complete BASIC syntax/manual** (grammar, variables, program storage format, token encoding) from this ROM area if you provide a larger ROM dump around the interpreter code.
