4.1 Register File (RF)  
‘ ’  
The 256-byte on chip RAM resides in location >0000 to >00FF ( > means hex) of the DMC73C168 s  
address space and is called the Register File (RF). The RAM is treated as registers by much of the  
instruction set and numbered R0-R255. The first two registers, R0 and R1, are also called the A and  
B registers respectively. Several instructions specify A or B as either the source or destination  
register ; e.g., STSP stores the contents of the Stack Pointer (SP) in the B register.  
Except where stated otherwise, any register in the Register File can be addressed as an 8-bit source or  
destination register. The stack is also located in the Register File. Refer to section 4.3 for information  
regarding the initialization of the Stack Pointer (SP) and stack definition in the Register File.  
4.2 Peripheral File (PF)  
The Peripheral File (PF) resides in location >0100 to >0132 of the DMC73C168 s address space.  
Peripheral File locations are numbered P0-P50. The PF registers are used for interrupt control, parallel  
I/O, timer control, PLL, IF counter, BEEP, SIO and A/D converter control.  
4.3 Peripheral RAM File (PRF)  
The Peripheral RAM file (PRF) resides in location >0140 to >01BF of DMC73C168 s address space.  
PRF will act a role P64-P191. Useage is for additional RAM, but addressing method is same as  
Peripheral File s.
