Renasas M32192 Flash 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:
