9.2 Interrupt Enable structure
Each interrupt source can be individually enabled or disabled by
setting or clearing a bit in the interrupt enable special function
register IE and IEA. All interrupt source can also be globally dis-
abled by clearing bit EA in IE.
Table 9-1 Interrupt Enable Register(IE: 0A8H) RESET VALUE:00000000B
Table 9-2 Description of the IE bits
Table 9-3 Interrupt Enable Register(IEA: 0A7H) RESET VALUE:0xxxxx00B
Table 9-4 Description of Enable Register(IEA: 0A7H)
