SYSTEM REGISTER
OVERVIEW
8-bit micro-controller
SONiX TECHNOLOGY CO., LTD
Page 36
Revision 1.94
The RAM area located in 80H~FFH bank 0 is system register area. The main purpose of system registers is to control
peripheral hardware of the chip. Using system registers can control I/O ports, timers and counters by programming.
The memory map provides an easy and quick reference source for writing application program. These system registers
accessing is controlled by the selected memory bank (RBANK = 0) or the bank 0 read/write instruction (B0MOV,
B0BSET, B0BCLR…).

Description
PFLAG = ROM page and special flag register.
P1W = Port 1 Wakeup register.
PnM = Port n input/output mode register.
INTRQ = Interrupt request register.
OSCM = Oscillator mode register.
TCnM = Timer n mode register.
STKP = Stack pointer buffer.
@YZ = RAM YZ indirect addressing index pointer.
Note:
a). All register names had been declared in SN8ASM assembler.
b). 1-bit register name had been declared in SN8ASM assembler with “F” prefix code.
c). When using instruction to check empty location, logic “H” will be returned.
d). “b0bset”, “b0bclr”, ”bset”, ”bclr” instructions only support “R/W” registers.
