2.7
Program Inhibit
Programming of multiple M87C257s in parallel with different data is also easily
accomplished. Except for E, all like inputs including G of the parallel M87C257 may be
common. A TTL low level pulse applied to a M87C257's E input, with VPP at 12.75V, will
program that M87C257. A high level E input inhibits the other M87C257s from being
programmed.
2.8
Program Verify
A verify (read) should be performed on the programmed bits to determine that they were
correctly programmed. The verify is accomplished with G at VIL, E at VIH, VPP at 12.75V and
VCC at 6.25V.
