4.4 UARTn Interrupt Enable Register (U0IER - 0xE000 C004, U2IER -
higher 8 bits of the divisor. A 0x0000 value is treated like a 0x0001 value as division by
zero is not allowed. The Divisor Latch Access Bit (DLAB) in UnLCR must be one in order
to access the UARTn Divisor Latches.

0xE007 8004, U3IER - 0xE007 C004 when DLAB = 0)
The UnIER is used to enable the three UARTn interrupt sources.
