Access to the on-chip FLASH for read is synchronized with I φ clock and is executed in one clock
cycle. For details on programming and erasing, see section 17, Flash Memory.
Access to the on-chip RAM for read/write is synchronized with I φ clock and is executed in one
clock cycle. For details, see section 18, RAM.
