18.2.7 Expanded External Interrupt Status Register (EEISTAT)
EEISTAT is a special function register (SFR) used to indicate the expanded external interrupt status.
The EEI3S bit to EEI0S bit is reset to "0" by writing "1" to the same number of bit in the EEINTC register.
The EEISTAT is the read-only register.

EEI0S These bits are used to indicate the expanded external interrupt status.
The relation of the bit number and the target external interrupt:
Bit 3 (EEI3S) : EXI11INT Interrupt
Bit 2 (EEI2S) : EXI10INT Interrupt
Bit 1 (EEI1S) : EXI9INT Interrupt
Bit 0 (EEI0S) : EXI8INT Interrupt
