43.3.23 UART 7816 Interrupt Enable Register (UARTx_IE7816)
The IE7816 register controls which flags result in an interrupt being issued. This register
is specific to 7816 functionality, the corresponding flags that drive the interrupts will not
assert when 7816E is not set/enabled. However, these flags may remain set if they
asserted while 7816E was set and not subsequently cleared. This register maybe read or
written at anytime.
Addresses: UART0_IE7816 is FFFF_8140h base + 19h offset = FFFF_8159h
