Reset Sources
The ATtiny24A/44A/84A has four sources of reset:
Power-on Reset. The MCU is reset when the supply voltage is below the Power-on Reset
threshold (V
POT)
External Reset. The MCU is reset when a low level is present on the RESET pin for longer
than the minimum pulse length when RESET function is enabled
Watchdog Reset. The MCU is reset when the Watchdog Timer period expires and the
Watchdog is enabled
Brown-out Reset. The MCU is reset when the supply voltage V
CC is below the Brown-out
Reset threshold (V
BOT) and the Brown-out Detector is enabled
8.2.1
Power-on Reset
A Power-on Reset (POR) pulse is generated by an on-chip detection circuit. The detection level
is defined in “System and Reset Characteristics” on page 176. The POR is activated whenever
V
CC is below the detection level. The POR circuit can be used to trigger the Start-up Reset, as
well as to detect a failure in supply voltage.
A Power-on Reset (POR) circuit ensures that the device is reset from Power-on. Reaching the
Power-on Reset threshold voltage invokes the delay counter, which determines how long the
device is kept in reset after V
CC rise. The reset signal is activated again, without any delay, when
V
CC decreases below the detection level.
