Register Description
8.4.1
MCUSR – MCU Status Register
The MCU Status Register provides information on which reset source caused an MCU Reset.
Bits 7:4 – Res: Reserved Bits
These bits are reserved bits in the ATtiny13 and will always read as zero.
Bit 3 – WDRF: Watchdog Reset Flag
This bit is set if a Watchdog Reset occurs. The bit is reset by a Power-on Reset, or by writing a
logic zero to the flag.
Bit 2 – BORF: Brown-out Reset Flag
This bit is set if a Brown-out Reset occurs. The bit is reset by a Power-on Reset, or by writing a
logic zero to the flag.
Bit 1 – EXTRF: External Reset Flag
This bit is set if an External Reset occurs. The bit is reset by a Power-on Reset, or by writing a
logic zero to the flag.
Bit 0 – PORF: Power-on Reset Flag
This bit is set if a Power-on Reset occurs. The bit is reset only by writing a logic zero to the flag.
To make use of the Reset Flags to identify a reset condition, the user should read and then reset
the MCUSR as early as possible in the program. If the register is cleared before another reset
occurs, the source of the reset can be found by examining the Reset Flags.
8.4.2
WDTCR – Watchdog Timer Control Register
Bit 7 - WDTIF: Watchdog Timer Interrupt Flag
This bit is set when a time-out occurs in the Watchdog Timer and the Watchdog Timer is config-
ured for interrupt. WDTIF is cleared by hardware when executing the corresponding interrupt
handling vector. Alternatively, WDTIF is cleared by writing a logic one to the flag. When the I-bit
in SREG and WDTIE are set, the Watchdog Time-out Interrupt is executed.
Bit 6 - WDTIE: Watchdog Timer Interrupt Enable
When this bit is written to one and the I-bit in the Status Register is set, the Watchdog Interrupt is
enabled. If WDE is cleared in combination with this setting, the Watchdog Timer is in Interrupt
Mode, and the corresponding interrupt is executed if time-out in the Watchdog Timer occurs.
If WDE is set, the Watchdog Timer is in Interrupt and System Reset Mode. The first time-out in
the Watchdog Timer will set WDTIF. Executing the corresponding interrupt vector will clear
WDTIE and WDTIF automatically by hardware (the Watchdog goes to System Reset Mode).
