5 / 53 page  CY7C63722C CY7C63723C CY7C63743C Document #: 38-08022 Rev. *E Page 5 of 53 ■ MOV A,DSPINIT Direct “Direct” address mode is used when the data operand is a variable stored in SRAM. In that case, the one byte address of the variable is encoded in the instruction. As an example, consider an instruction that loads A with the contents of memory address location 0x10h: ■ MOV A, [10h] In normal usage, variable names are assigned to variable addresses using “EQU” statements to improve the readability of the assembler source code. As an example, the following code is equivalent to the example shown above. ■ buttons: EQU 10h ■ MOV A, [buttons] Indexed “Indexed” address mode allows the firmware to manipulate arrays of data stored in SRAM. The address of the data operand is the sum of a constant encoded in the instruction and the contents of the “X” register. In normal usage, the constant will be the “base” address of an array of data and the X register will contain an index that indicates which element of the array is actually addressed. ■ array: EQU 10h ■ MOV X,3 ■ MOV A, [x+array] This would have the effect of loading A with the fourth element of the SRAM “array” that begins at address 0x10h. The fourth element would be at address 0x13h. Instruction Set Summary Refer to the CYASM Assembler User’s Guide for detailed infor- mation on these instructions. Note that conditional jump instruc- tions (i.e., JC, JNC, JZ, JNZ) take five cycles if jump is taken, four cycles if no jump.
