Resets
Technical Data
5.4.2 I/O Port Registers
A reset has these effects on input/output (I/O) port registers:
Clears bits DDRA7–DDRA0 in data direction register A so that
port A pins are inputs
Clears bits PDIA7–PDIA0 in pulldown register A, turning on port A
pulldown devices (if pulldown devices are enabled by mask
option)
Clears bits DDRB1 and DDRB0 in data direction register B so that
port B pins are inputs
Clears bits PDIB1 and PDIB0 in pulldown register B, turning on
port B pulldown devices (if pulldown devices are enabled by mask
option)
Has no effect on port A or port B data registers
5.4.3 Timer
A reset has these effects on the multifunction timer:
Clears the timer status and control register
Clears the timer counter register
5.4.4 COP Watchdog
A reset clears the COP watchdog timeout counter.
