Write Fuse High bits

1010 1100

1010 1000

xxxx xxxx

iiii iiii

Set bits = “0” to program, “1” to

unprogram. See Table 25-5 on page

283 for details.

Write Extended Fuse Bits

1010 1100 1010 0100 xxxx xxxx xxxx xxii Set bits = “0” to program, “1” to

unprogram. See Table 25-4 on page

282 for details.

Read Fuse bits

0101 0000

0000 0000

xxxx xxxx

oooo oooo

Read Fuse bits. “0” = programmed, “1”

= unprogrammed. See Table XXX on

page XXX for details.

Read Fuse High bits

0101 1000

0000 1000

xxxx xxxx

oooo oooo

Read Fuse High bits. “0” = pro-

grammed, “1” = unprogrammed. See

Table 25-5 on page 283 for details.

Read Extended Fuse Bits

0101 0000 0000 1000 xxxx xxxx oooo oooo Read Extended Fuse bits. “0” = pro-

grammed, “1” = unprogrammed. See

Table 25-4 on page 282 for details.

Read Calibration Byte

xxxx xxxo

If o = “1”, a programming operation is

still busy. Wait until this bit returns to

“0” before applying another command.

Note: a = address high bits, b = address low bits, H = 0 - Low byte, 1 - High Byte, o = data out, i = data in, x = don’t care
