The MIW circuit can be used with the I/O ports configured as both an input and output. The MIW configuration and function is
the same for both I/O configurations. However, when using the MIW circuit to wake the device from Halt/Idle Mode the
wakeup I/O port must be configured as an input, otherwise the device will never exit the mode.

3. Hardware interrupts are not executed by the microcontroller core unless the Global Interrupt enable (G) flag of the Status register is set. Refer to the
4. No other hardware interrupts will be executed, aside from the software interrupt instruction, until the MIW hardware interrupt is no longer executed. Refer to the
5. Available only on the 14-pin package option.
6. The PWMOFF and PWMINT signals are the outputs from the Programmable Comparator’s Digital Filter circuit. Refer to
