Chapter 3 Software Environment
Chapter 3 Software Environment
This chapter describes the software environment required for the user to rewrite Code Flash by using the FCL.
3.1 FCL Sections
The functions, constants, and variables used in the FCL are allocated to the specified sections. Table 3-1,
Sections Available for the FCL , lists sections defined by the FCL. Since the code flash is not accessible during
execution of a command Note 1, place sections to be used during execution of a command in the on-chip RAM.
Sections for which “RAM” is specified in the “Location” column in table 3-1 are used when commands are executed.
Table 3-1 Sections Available for the FCL
Section name

<R> R_FCL_CONST

FCL’s constant area (FCL version information)
R_FCL_CODE_ROM
R_FCL_CODE_ROMRAMNote2
R_FCL_CODE_RAMNote2

FCL’s program area
RAM area used by FCL
R_FCL_DATA
R_FCL_CODE_RAM_USRINTNote2Note3
R_FCL_CODE_RAM_USRNote2Note3
R_FCL_CODE_RAM_EX_PROTNote3
Interrupt vector during execution of a
command Note 1
User program that controls FCL
System reservation (only definition)
Note 1:
Note 2:
Note 3:
For information on the execution of a command, see section 5.4.1, During Execution of Command/Busy.
These sections can be placed in the code flash in some devices. See section 5. 6. 4, Background
Operation (BGO).
These sections are user sections prepared on the FCL side. Even if they are not used, their names are
referenced by the FCL in some cases. Therefore, if an error of insufficient sections occurs when linking,
define applicable sections.
