The MCU Control Register contains control bits for general Microcontroller Unit
functions.
• Bit 7 – JTD - JTAG Interface Disable
When this bit is zero, the JTAG interface is enabled if the JTAGEN Fuse is
programmed. If this bit is one, the JTAG interface is disabled. In order to avoid
unintentional disabling or enabling of the JTAG interface, a timed sequence must be
followed when changing this bit: The application software must write this bit to the
desired value twice within four cycles to change its value. Note that this bit must not be
altered when using the On-chip Debug system.
The MCU Status Register provides information on which reset source caused an MCU
reset.
