3.1.1 Internal program memory space
The internal program memory space stores the program and table data.
The RL78/F13 and RL78/F14 products incorporate internal ROM (flash memory), as shown below.
Table 3-2. Internal ROM Capacity
Part Number Internal ROM
Structure Capacity
R5F10AmA (m = 6, A, B, G) Flash memory 16 Kbytes (00000H-03FFFH)
R5F10AmC (m = 6, A, B, G, L) 32 Kbytes (00000H-07FFFH)
R5F10BmC (m = A, B, G, L)
R5F10AmD (m = 6, A, B, G, L) 48 Kbytes (00000H-0BFFFH)
R5F10BmD (m = A, B, G, L)
R5F10PmD (m = A, B,G)
R5F10AmE (m = 6, A, B, G, L, M) 64 Kbytes (00000H-0FFFFH)
R5F10BmE (m = A, B, G, L, M)
R5F10PmE (m = A, B, G, L, M, P)
R5F10AmF (m = G, L, M) 96 Kbytes (00000H-17FFFH)
R5F10BmF (m = A, B, G, L, M)
R5F10PmF (m = G, L, M, P)
R5F10AmG (m = G, L, M) 128 Kbytes (00000H-1FFFFH)
R5F10BmG (m = A, B, G, L, M)
R5F10PmG (m = G, L, M, P)
R5F10PmH (m = G, L, M, P) 192 Kbytes (00000H-2FFFFH)
R5F10PmJ (m = G, L, M, P) 256 Kbytes (00000H-3FFFFH)
The internal program memory space is divided into the following areas.
(1) Vector table area
The 128-byte area 00000H to 0007FH is reserved as a vector table area. The program start addresses for branch upon
reset or generation of each interrupt request are stored in the vector table area. Furthermore, the interrupt jump address
is a 64 K address of 00000H to 0FFFFH, because the vector code is assumed to be 2 bytes.
Of the 16-bit address, the lower 8 bits are stored at even addresses and the higher 8 bits are stored at odd addresses.
To use the boot swap function, set a vector table also at 02000H to 0207FH.
Table 3-3 lists the vector table. “” indicates an interrupt source which is supported. “” indicates an interrupt source
which is not supported.
