MEMORY ORGANIZATION
The PIC10F200/202/204/206 memories are organized
into program memory and data memory. Data memory
banks are accessed using the File Select Register
(FSR).

Program Memory Organization for
the PIC10F200/204
The PIC10F200/204 devices have a 9-bit Program
Counter (PC) capable of addressing a 512 x 12
program memory space.

Reset Vector
0000h
Only the first 256 x 12 (0000h-00FFh) for the
PIC10F200/204 are physically implemented (see
On-chip Program
Memory
Figure 4-1). Accessing
a location above these
boundaries will cause a wraparound within the first
256 x 12 space (PIC10F200/204). The effective
Reset vector is at 0000h (see Figure 4-1). Location
00FFh (PIC10F200/204) contains the internal clock
oscillator calibration value. This value should never
be overwritten.

Note 1: Address 0000h becomes the
effective Reset vector. Location
00FFh contains the MOVLW XX
internal oscillator calibration value.
