Lattice Semiconductor
ispVM System and ispVME takes care of the detail to program the SPI Flash devices via the JTAG port. The detail
task is shown in the waveform diagram on on
Table 17-7. Description of the Hare-wired JTAG SPI Flash Programming IP

RTI DRS IRS CTR
The standard method to set the JTAG state machine to a known state.
Shift in the PROGRAM_SPI instruction (OPCODE = 0x0X). Indicate bit 0 first shifting direction.
The 4-pin JTAG port is connected to the 4-pin SPI interface. SLCK following TCK indicate
connection is made.
Send in the command to erase a sector or shift in one page of programming data. The FPGA
respond by driving the CSSPIN pin to low to gate on SCLK, SPID0, and SISPI.
Drive the CSSPIN to high to command the SPI Flash device to start the erase or program-
ming action. Wait for the required erase or programming delay time then poll the complete
status. Consult the SPI Flash datasheet for the polling method required.
Loop around to erase by sectors and programming by pages.
