Merge pull request #57 from wjhun/27C040-pgmtype 
update PgmType for 27C040 EPROM
 2023-07-21 11:42:33 -04:00

a42ecc2719 update PgmType for 27C040 EPROM 
The (AMD/Atmel) 27C040 EPROM doesn't have a dedicated Write Enable (WE),
instead sharing the same pin for CE# and PGM#. This updates the PromDevice27
line for this device to use the E27C_PGM_CE PgmType.

This configuration has been successfully used to read, program and verify an
AM27C040 device. A +12.75V voltage was applied to Vpp during the duration of
device programming.
