INTERRUPT_PROTECT (IEC0bits.U1TXIE=0);
Note:
For modification of the Interrupt 1 setting, the
INTERRUPT_PROTECT macro can be used.
This macro disables interrupts before executing
the desired expression, as shown in Example 5.
This macro is not distributed with the compiler.

If you are using a MPLAB C30 compiler
version earlier than version 1.32, you may
still use the macros by adding them to your
application.
