hi any one.
how can tell me about this question.
when you used macro code 8051(opcode) for read and write
into chip for example(sle4428) .
you should send 3 byte(word command) for protocol and reader comunications parameters that it is write into all document for smart card but there is not pointer the main detail about address byte.
there is main question .that's when we read chip we are not allow read 256 byte .this means 00h until 0ffh address then
if we needd read >256 what we doing?
this is first idea that we define 4 page *256 byte.this ok.
but we how set command control address with page.
all of command is better for smart card with 256 byte.
and is not good driver for smart cards under 256 byte.
when you read PSC for sle4428 this code is address 1023 & 1024
so when you send READ word control command :
(70h+0xff+noeffect) and send this command you can only point
0xff address and you can not entry under 0xff .
and if you use page number you cannot xor page number with address.
then what is answare?
if any have answer please send sample or detail to my email
