Reneas M32192F8 Microcontroller Internal Flash Memory Programming
Renesas Microcontroller M32192F8 Internal Flash Memory Questions.
1. Can a cell be programmed more than once? I define cell size to be 8 bytes because 8 bytes are programmed at a time. For example, if I program 0x55AA to a cell and again program 0x55AA to the same cell, is that allowed?
2. Once Flash chip is in erase/write enable mode, can it be read by dereferencing an address. Or do I have to command it to read mode in order to read. If it needs to be commanded to read mode in order to read, then do I have to put it back in erase/write mode in order to program.
Please see chapter 6 at the following link:

I cannot beileve it, but I cannot find the manual. I find the page, but I cannot find the correct pdf. I see product specifications, but no manual that describes the flash programming????? Can you give more specific details as to what to click on. I am surprised that I cannot find it???

Could you go to www.renesas.com. Then, click on M32R and it will take you to M32192 Manual. Please see chapter 6 of this manual.
For all of our platforms, we enable flash chip for erase and program during initialization. While chip is in this enabled for erase and program, we program the chip and also read the chip. I mean we just read by dereferencing memory address. Can we do that with this flash memory.
