Precautions concerning the use of on-board programming modes and PROM mode are
summarized below.
1. Program with the specified voltages and timing.
2. Before programming, check that the chip is correctly mounted in the PROM programmer.
3. Do not touch the socket adapter or chip while programming. Touching either of these can
4. Set H'FF as the PROM programmer buffer data for the following addresses:

Applied voltages in excess of the rating can permanently damage the device. In particular,
insure that the peak overshoot of the PROM programmer does not exceed the maximum rating
of 13 V.
Overcurrent damage to the device can result if the index marks on the PROM programmer
socket, socket adapter, and chip are not correctly aligned.

H8/3643F: H'6000 to H'1FFFF
H8/3642AF: H'4000 to H'1FFFF
The size of the PROM area is 32 kbytes in the H8/3644F, 24 kbytes in the H8/3643F, and 16
kbytes in the H8/3642AF. The addresses shown above always read H'FF, so if H'FF is not
specified as programmer data, a block error will occur.
