Do not write logic 1s to reserved bits. These bits may be used in future 80C51 family products to invoke
new features. In that case, the reset or inactive value of the new bit will be logic 0, and its active value will
be logic 1. The value read from a reserved bit is indeterminate.

Description
Global disable. If EA = 0, all interrupts are disabled; If EA = 1, each
interrupt can be individually enabled or disabled by setting or clearing
its enable bit.
Not implemented. Reserved for future use
Timer 2 interrupt enable. ET2 = 1 enables the interrupt; ET2 = 0
disables the interrupt.
Serial port interrupt enable. ES = 1 enables the interrupt; ES = 0
disables the interrupt.
Timer 1 interrupt enable. ET1 = 1 enables the interrupt; ET1 = 0
disables the interrupt.
External interrupt 1 enable. EX1 = 1 enables the interrupt; EX1 = 0
disables the interrupt.
Timer 0 interrupt enable. ET0 = 1 enables the interrupt; ET0 = 0
disables the interrupt.
External interrupt 0 enable. EX0 = 1 enables the interrupt; EX0 = 0
disables the interrupt.
Description
