7.
Write the page using programming instruction 2g.
8.
Poll for Flash write complete using programming instruction 2h, or wait for t
WLRH_FLASH
9.
Repeat steps 3 to 7 until all data have been programmed.
A more efficient data transfer can be achieved using the PROG_PAGELOAD instruction:
1.
Enter JTAG instruction PROG_COMMANDS.
2.
Enable Flash write using programming instruction 2a.
3.
Load the page address using programming instructions 2b and 2c. PCWORD (refer to
4.
Enter JTAG instruction PROG_PAGELOAD.
5.
Load the entire page by shifting in all instruction words in the page, starting with the LSB
of the first instruction in the page and ending with the MSB of the last instruction in the
page.
6.
Enter JTAG instruction PROG_COMMANDS.
7.
Write the page using programming instruction 2g.
8.
Poll for Flash write complete using programming instruction 2h, or wait for t
WLRH_FLASH
9.
Repeat steps 3 to 8 until all data have been programmed.
Reading the Flash
1.
Enter JTAG instruction PROG_COMMANDS.
2.
Enable Flash read using programming instruction 3a.
3.
Load address using programming instructions 3b and 3c.
4.
Read data using programming instruction 3d.
5.
Repeat steps 3 and 4 until all data have been read.
A more efficient data transfer can be achieved using the PROG_PAGEREAD instruction:
1.
Enter JTAG instruction PROG_COMMANDS.
2.
Enable Flash read using programming instruction 3a.
3.
Load the page address using programming instructions 3b and 3c. PCWORD (refer to
4.
Enter JTAG instruction PROG_PAGEREAD.
5.
Read the entire page by shifting out all instruction words in the page, starting with the
LSB of the first instruction in the page and ending with the MSB of the last instruction in
the page. Remember that the first 8 bits shifted out should be ignored.
6.
Enter JTAG instruction PROG_COMMANDS.
7.
Repeat steps 3 to 6 until all data have been read.
