Warnings
1. Always specify addresses $0000 to $7FFF when programming with a PROM programmer. If address
$8000 or higher is accessed, the PROM may not be programmed or verified correctly. Set all data in
unused addresses to $FF.
Note that the plastic-package version cannot be erased and reprogrammed.
2. Make sure that the PROM programmer, socket adapter, and LSI are aligned correctly (their pin 1
positions match), otherwise overcurrents may damage the LSI. Before starting programming, make sure
that the LSI is firmly fixed in the socket adapter and the socket adapter is firmly fixed onto the
programmer.
3. PROM programmers have two voltages (V
PP
): 12.5 V and 21 V. Remember that ZTAT
devices
require a V
PP
of 12.5 V—the 21-V setting will damage them. 12.5 V is the Intel 27256 setting.
Programming and Verification
The built-in PROM of the MCU can be programmed at high speed without risk of voltage stress or damage
to data reliability.
Programming and verification modes are selected as listed in table 30.
For details of PROM programming, refer to the following Notes on PROM Programming section.
