Is there anyone who has used P89C662HBA?Please teld me your way of programming code by serial port or parallel tool.Thank very much.
OK,who can tell me set security bit1、 set security bit2 and set security bit3 meaning,if I choose any one when programming code,what will happen to MCU;
The security bits are described in the P89C66X user manual from NXP, table 16 in the "In-System Programming (ISP) and In-Application Programming (IAP)" chapter.
For programming this part using the serial port you can use Flash Magic.
