5SYSTEM REGISTER  
OVERVIEW  
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.  
R = Working register and ROM look-up data buffer.  
Y, Z = Working, @YZ and ROM addressing register.  
Pn = Port n data buffer.  
INTEN = Interrupt enable register.  
PCH, PCL = Program counter.  
TCnC = Timer n counting register.  
STKP = Stack pointer buffer.  
TC1R= TC1 8-bit reload register.  
@YZ = RAM YZ indirect addressing index pointer.  
STK0~STK3 = Stack 0 ~ stack 3 buffer.  
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.
