Register 8: GPIO Masked Interrupt Status (GPIOMIS), offset 0x418
The GPIOMIS register is the masked interrupt status register. If a bit is set in this register, the
corresponding interrupt has triggered an interrupt to the interrupt controller. If a bit is clear, either
no interrupt has been generated, or the interrupt is masked.
Note that if the Port B GPIOADCCTL register is cleared, PB4 can still be used as an external trigger
for the ADC. This is a legacy mode which allows code written for previous devices to operate on
this microcontroller.
GPIOMIS is the state of the interrupt after masking.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
GPIO µDMA Done Masked Interrupt Status
Value Description
0 The µDMA done interrupt is masked or has not occurred.
1 An unmasked µDMA done interrupt has occurred.
This bit is cleared by writing a 1 to the DMAIC bit in the GPIOICR register.
