ROM Verification

The on-chip memory can be read out for ROM verification.

The address of the program memory location to be read is

applied to Port 1 and pins P2.3-P2.0. The other pins should

be held at the “Verify” level. The contents of the addressed

locations will be emitted on Port 0. External pullups are

required on Port 0 for this operation. Figure 10 shows the

setup to verify the program memory.
