• Description: Atmel CryptoAuthentication Product Authentication Chip
• Manufacturer: ATMEL [ATMEL Corporation]

6.6
PauseLong
Forces the chip into the pause state until the watchdog timer expires, after which it will automatically enter into the sleep state.
During execution of this command and while in the pause state the chip will ignore all activity on the IO signal. This command
is used to prevent bus conflicts in a system that also includes other AT88SA102S chips or a CryptoAuthentication host chip
sharing the same signal wire.
Table 6-13. Input Parameters
The Selector parameter provides a mechanism to select which device will pause if there are multiple devices on the bus:

Data

If the selector parameter is 0x00, then every AT88SA102S chip receiving this command will go into the pause state
If any of the bits of the selector parameter are set, then the chip will read the values of Fuse[84-87] and go into the
and no chip will return a success code.
pause state only if those fuse values match the least significant 4-bits of the selector parameter. If the chip does not
go into the pause state, it returns an error code of 0x0F. Otherwise it goes into the pause state and never returns
any code.
