The System Special Registers are designed to complete CPU Core functions, and consists of indirect address,
indirect address pointer, status register, work register, interrupt flag, and interrupt control register.

The IND[1:0] registers at data memory address are not physical registers. Any instruction using the IND[1:0]
Indirect addressing pointers FSR0 and FSR1 correspond to IND0 and IND1 respectively.
Use contents of FSR0 (IND0: Address 00H) or FSR1 (IND1: Address 01H) to address data memory.
The STATUS register contains the arithmetic status of the ALU.
WORK : Store temporary data.
GIE : Global interrupt enable.
VDDIF, VDDIE : VDD > VBAT Interrupt flag and enable. Used when there is only VBAT and VDD is off.VDDIF
TMIF, TMIE: 8-bit Timer Interrupt flag and enable.
DC: Digit Carry Flag, for ADDWF(C) and SUBWF(C).
C : Carry Flag.(~Borrow)
Z : Zero Flag.

0 = No carry-out from the 4th low order bit of the result.
0 = The result of an arithmetic or logic operation is not zero.
1 = A carry-out from the 4th low order bit of the result occurred.
1 = The result of an arithmetic or logic operation is zero.
