Does anyone have a suitable startup file or at least the major setting that should be made to the startup file to make maximum use of the memory model of the P89V51RD2?

P89V51Rx2/P89LV51Rx2 / Re: putting P89V51RD2 in 6 clocks per machine cycle

Setting the FST register to 0x08 should make it work with 6clocks/cycle. Am i correct?

Hi, i just designed a programmer circuit for the P89V51RD2. I am just going to use the RX and TX to program the device. Since i am not using the PSEN pin shall i leave it floating or shall i connect it to +5V or GND??
