UART INTERRUPT MASK REGISTER
Interrupt mask register contains the information of the masked interrupt. If a specific bit is set to 1, interrupt
request signal to Interrupt Controller is not generated even though corresponding interrupt is generated. (Note
that even in such a case, the corresponding bit of UINTSPn register is set to 1). If the mask bit is 0, the interrupt
request can be serviced from the corresponding interrupt source
(Note that even in such a case, the corresponding bit of UINTSPn register is set to 1).
