Low Voltage Detection
Reset Register Definitions
PS022825-0908
Stop Mode Recovery Using the External RESET Pin
Reset Status Register
When the Z8 Encore! XP F082A Series device is in STOP mode and the external RESET
pin is driven Low, a system reset occurs. Because of a glitch filter operating on the RESET
pin, the Low pulse must be greater than the minimum width specified, or it is ignored. See
Electrical Characteristics
In addition to the Voltage Brownout (VBO) Reset described above, it is also possible to
generate an interrupt when the supply voltage drops below a user-selected value. For
details about configuring the Low Voltage Detection (LVD) and the threshold levels avail-
able, see
pin product versions only.
When the supply voltage drops below the LVD threshold, the LVD bit of the Reset Status
(RSTSTAT) register is set to one. This bit remains one until the low-voltage condition
goes away. Reading or writing this bit does not clear it. The LVD circuit can also generate
an interrupt when so enabled, see
is NOT latched, so enabling the interrupt is the only way to guarantee detection of a
transient low voltage event.
The LVD functionality depends on circuitry shared with the VBO block; therefore,
disabling the VBO also disables the LVD.
The following sections define the Reset registers.
The Reset Status (RSTSTAT) register is a read-only register that indicates the source of
the most recent Reset event, indicates a Stop Mode Recovery event, and indicates a
Watchdog Timer time-out. Reading this register resets the upper four bits to 0.
This register shares its address with the Watchdog Timer control register, which is
write-only (see
initiate Stop Mode Recovery without being written to the Port Input Data register or
without initiating an interrupt (if enabled for that pin).
