18.7
The flash memory has the following registers.
Programming/Erasing Interface Registers:
• Flash code control/status register (FCCS)
• Flash program code select register (FPCS)
• Flash erase code select register (FECS)
• Flash key code register (FKEY)
• Flash MAT select register (FMATS)
• Flash transfer destination address register (FTDAR)
Programming/Erasing Interface Parameters:
• Download pass and fail result parameter (DPFR)
