19.2.1 Allocation of DTC Control Data Area and DTC Vector Table Area
The DTCBAR register is used to set the 256-byte area where DTC control data and the vector table within the RAM area.
Figure 19-2 shows a memory map example when DTCBAR register is set to FBH.
In the 192-byte DTC control data area, the space not used by the DTC can be used as RAM.
Figure 19-2. Memory Map Example when DTCBAR Register is Set to FBH
The areas where the DTC control data and vector table can be allocated differ depending on the usage conditions.
Cautions 1. It is prohibited to use the general-purpose register (FFF00H to FFEE0H) space as the DTC control
data area or DTC vector table area.
2. The 18-byte area between the DTC vector table area and the DTC control data area is reserved for
use when the number of DTC activation sources is expanded.
3. The internal RAM area in the following products cannot be used as the DTC control data area or
DTC vector table area when using the self-programming function and data flash function.
R5F10AmE (m = 6, A, B, G, L) : FEF00H to FF2FFH
R5F10PmF (m = G, L, M) : FDF00H to FE2FFH
R5F10AmG (m = G, L, M), R5F10BnG (n = A, B, G, L, M) : FDF00H to FE2FFH
R5F10PmJ (m = G, L, M, P) : FAF00H to FB2FFH
4. The internal RAM area in the following products cannot be used as the DTC control data area or
DTC vector table area when using the tracing function of on-chip debugging.
R5F10AmE (m = 6, A, B, G, L), R5F10AnD (n = 6, A, B, G, L) : FF300H to FF37FH
R5F10AmG (m = G, L, M), R5F10BnG (n = A, B, G, L, M) : FE300H to FE4FFH
R5F10PmF (m = G, L, M) : FE300H to FE4FFH
R5F10PmJ (m = G, L, M, P) : FB300H to FB4FFH
5. The internal RAM in the following products cannot be used as stack memory when the hot plug-in
function is used or when the DTC is in use for the RRM or DMM function.
R5F10AmD, R5F10AmE (m = 6, A, B, G, L) : FF400H to FF42FH
R5F10AmG (m = G, L, M), R5F10BnG (n = A, B, G, L, M) : FE500H to FE52FH
R5F10PmF (m = G, L, M) : FE500H to FE52FH
R5F10PmJ (m = G, L, M, P) : FB500H to FB52FH
