Re: how to judge that the class byte of APDU command is valid?
Filter by the following function:
int8_t apdu_is_valid_cla(void)
{
return (int8_t)((((g_apdu_info.cla) & 0xE0) != 0x20) && ((g_apdu_info.cla) != 0xFF));
}
int8_t apdu_is_valid_cla(void)
{
return (int8_t)((((g_apdu_info.cla) & 0xE0) != 0x20) && ((g_apdu_info.cla) != 0xFF));
}
