INTERNAL MEMORY
6.4 Registers Associated with the Internal Flash Memory
6.4.2 Flash Status Registers
The 32170 has two registers to indicate the flash memory status, one of which is Flash Status
Register 1 (FSTAT1) located in the SFR area (address: H'0080 07E1), and the other is Flash Status
Register 2 (FSTAT2) included in the flash memory itself. When programming or erasing the flash
memory, use these two status registers (FSTAT1, FSTAT2) to control the program/erase
operations.

The Flash Status Register 1 (FSTAT1) is a read-only status register used to know the execution
status of whether the flash memory is being programmed or erased. When the FSTAT bit = 0, it
means that the flash memory is being programmed or erased, during which time any operation to
program the flash memory area is disabled.
