Programming Model
14-Bit Program Counter (PC)
The 14-bit program counter (PC) allows access to up to 8 KB of
PROM available with the CY7C64x13C architecture. The top
32 bytes of the ROM in the 8 Kb part are reserved for testing
purposes. The program counter is cleared during reset, such that
the first instruction executed after a reset is at address 0x0000h.
Typically, this is a jump instruction to a reset handler that
initializes the application (see
The lower eight bits of the program counter are incremented as
instructions are loaded and executed. The upper six bits of the
program counter are incremented by executing an XPAGE
instruction. As a result, the last instruction executed within a
256-byte “page” of sequential code should be an XPAGE

instruction. The assembler directive “XPAGEON” causes the
assembler to insert XPAGE instructions automatically. Because
instructions can be either one or two bytes long, the assembler
may occasionally need to insert a NOP followed by an XPAGE
to execute correctly.
The address of the next instruction to be executed, the carry flag,
and the zero flag are saved as two bytes on the program stack
during an interrupt acknowledge or a CALL instruction. The
program counter, carry flag, and zero flag are restored from the
program stack during a RETI instruction. Only the program
counter is restored during a RET instruction.
The program counter cannot be accessed directly by the
firmware. The program stack can be examined by reading SRAM
from location 0x00 and up.
