Special function registers (SFRs) are allocated from address 00000h to 003FFh and from 0D000h to
0D7FFh. Peripheral function control registers are located here. All blank areas within SFRs are reserved.
Do not access these areas.
Internal RAM is allocated from address 00400h and higher, with 10 KB of internal RAM allocated from
00400h to 02BFFh. Internal RAM is used not only for data storage, but also for the stack area when
subroutines are called or when an interrupt request is accepted.
The internal ROM is flash memory. Three internal ROM areas are available: data flash, program ROM 1,
and program ROM 2.
The data flash is allocated from 0E000h to 0FFFFh. This data flash area is mostly used for data storage, but
can also store programs.
Program ROM 2 is allocated from 10000h to 13FFFh. Program ROM 1 is allocated from FFFFFh and lower,
with the 64 KB program ROM 1 area allocated from address F0000h to FFFFFh.
The special page vectors are allocated from FFE00h to FFFD7h. They are used for the JMPS and JSRS
instructions. Refer to the M16C/60, M16C/20, M16C/Tiny Series Software Manual for details.
The fixed vector table for interrupts is allocated from FFFDCh to FFFFFh.
The 256 bytes beginning with the start address set in the INTB register compose the relocatable vector table
for interrupts.
