Questions answered in these manuals
What are the supported MCU models for ISP programming?
The supported models are MPC89L(E)51/52/53, MPC89L(E)54/58/515, MPC82L(E)52, MPC82L(E)54, MPC82G516, MG84FL54, and MG84FL516.
What is the required ISP memory size for MPC82L(E)54 chips?
The ISP memory must be set to 1.5K bytes for MPC82L(E)54 chips.
How do I load the ISP code into the programmer buffer?
Select “Load File to Programmer Buffer” and choose the appropriate ISP_Code binary (e.g., ISP_Code_v5.00.bin for MPC89/82 series).
Which pin is used for ISP data transfer?
The ISP mode uses the P3.1 pin of the target MCU as the DTA (data) line.
What is the operating voltage range of the MA82G5A64?
The device operates from 2.0 V to 5.5 V.
How many 16‑bit timers are available?
The microcontroller provides four 16‑bit timers/counters.
