hi all any body
if you read data sheet for gpm8k/sle4428 this document detail apdu command for cards 1k byte.
this commands Consist of CLA INS A1 A2 LEN .
This data sheet said when you attempt to read or write into chip
we must select page number(0 or 1 or 2 or 3) into parameter A1 and address start into A2 or when read and write into protect area A1=80+page number A2=address start and word command is 3 byte that Consist of 1 byte command(01110011) 1byte address
and 1byte(for read no effect and write DATA INPUT).
BUT NOT POINT THIS case that byte address how define or contain (page and address start).
control this word command into the 8051 macro code is very
hard Especially verify psc code

if any known and have any sample for this problems i Gladness
if contact with me .
best regards.
