ISPEN : ISP Enable Bit (Read Only) ISP function enable. Note: This bit is read only to show ISP function enable.
bits : 0 - 0 (1 bit)
access : read-only

Enumeration:

End of enumeration elements list.

APUEN : APROM Update Enable Bit (Write Protect) Note: This bit is write protected. Refer to the SYS_REGLCTL register.
bits : 3 - 3 (1 bit)
access : read-write

Enumeration:

End of enumeration elements list.

NS_ISPFF : Non-sec ISP Fail Flag (Write Protect) This bit is set by hardware when a triggered ISP meets any of the following conditions: This bit needs to be cleared by writing 1 to it. APROM writes to itself if APUEN is set to 0. Page Erase command at LOCK mode with ICE connection Erase or Program command at brown-out detected Destination address is illegal, such as over an available range. Invalid ISP commands Read any content of boot loader with ICE connection ISP CMD in XOM region, except xom page erase and chksum command The wrong setting of page erase ISP CMD in XOM Violate XOM setting one time protection Page erase ISP CMD in Secure region setting page Page erase, mass erase, multi-word program or 64-bit word program in OTP NS_ISP Conflict Error Note: This bit is write protected. Refer to the SYS_REGLCTL register.
bits : 6 - 6 (1 bit)
access : read-write

NS_INTEN : Non-secure ISP Interuppt Enable Bit Note: This bit is write protected. Refer to the SYS_REGLCTL register.Before use INT,user need to clear the INTFLAG(FMC_ISPSTS[24]) make sure INT happen at correct time.

NS_ISPADDR : Non-sec ISP Address The M2354 series is equipped with embedded Flash. ISPADDR[1:0] must be kept 00 for ISP 32-bit operation. For CRC32 Checksum Calculation command, this field is the Flash starting address for checksum calculation, 2 Kbytes alignment is necessary for CRC32 checksum calculation. For Flash32-bit Program, ISP address needs word alignment (4-byte). For Flash 64-bit Program, ISP address needs double word alignment (8-byte). Non-sec ISP address must be active at Non-sec region.
bits : 0 - 31 (32 bit)
access : read-write

NS_ISPBUSY : Non-sec ISP Busy Flag (Read Only) Write 1 to start ISP operation and this bit will be cleared to 0 by hardware automatically when ISP operation is finished. This bit is the mirror of ISPGO(FMC_ISPTRG[0]).
bits : 0 - 0 (1 bit)
access : read-only
