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 spaces within SFRs are reserved,
so do not access any blank spaces.
The internal RAM is allocated from address 00400h to superior direction. For example, a 8-Kbyte internal
RAM is addressed from 00400h to 023FFh. The internal RAM is used not only for data storage but also for
stack area when subroutines are called or when interrupt request are acknowledged.
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 addressed from 0E000h to 0FFFFh. This data flash space is used not only for data storage
but also for program storage.
Program ROM 2 is assigned addresses 10000h to 13FFFh. Program ROM 1 is assigned addresses
FFFFFh to inferior direction. For example, the 64-Kbyte program ROM 1 space has addresses F0000h to
FFFFFh.
The special page vectors are assigned addresses FFE00h to FFFD7h. They are used for the JMPS
instruction and JSRS instruction. Refer to the M16C/60, M16C/20, M16C/Tiny Series Software Manual for
details.
The fixed vector table for interrupts, ID code write address, OFS1 address and OSF2 address are assigned
addresses FFFDBh to FFFFFh.
The 256 bytes beginning with the start address set in the INTB register compose the relocatable vector table
for interrupts.

Notes:
1. Do not access the reserved areas.
2. The figure above applies under the following conditions:
-The PM10 bit in the PM1 register is set to 1 (addresses from 0E000h to 0FFFFh are used as data flash)
-The PRG2C0 bit in the PRG2C register is set to 0 (program ROM 2 enabled)
