*1 Up to the number of "Total points of pointer device area" - "Number of points of global pointer".
*2 The default number of points is 32768 for the R120CPU, R120ENCPU, R120PCPU, R120PSFCPU, and R120SFCPU.
*3 The default number of points is 8192 for the R120CPU, R120ENCPU, R120PCPU, R120PSFCPU, and R120SFCPU.
*4 The default number of points is 16384 for the R120CPU, R120ENCPU, R120PCPU, R120PSFCPU, and R120SFCPU.
Specify a pointer number which is equal to or lower than "(end number of the pointer range specified in the
parameter) - (number of points of the global pointers)".
