Preliminary
2002 Microchip Technology Inc.
The HCS365 has an onboard nonvolatile EEPROM.
This EEPROM is used to store user programmable
data and the synchronization counter. The data is pro-
grammed at the time of production and includes the
security related information such as encoder keys,
serial numbers, discrimination values, and seed val-
ues. All the security related options are read protected.
The initial counter value is also programmed at the time
of production. From then on the device maintains the
counter itself. The HCS365 has built in redundancy for
protection and can recover from counter corruption.
The counter will not increment if the previous write was
corrupted by low voltage RESET or power failure dur-
ing T
PLL
. Instead, the counter will revert back to the
previous count and the HCS370 will attempt to correct
the bad bits. This will continue on every button press
until the voltage increases and the counter is success-
fully corrected.
