When an External Interrupt 0-7 is occurred, the flag becomes
‘1’.The flag is cleared
only by writing
‘0’ to the bit. So, the flag should be cleared by software.
0
External Interrupt0 ~ 7 not occurred
1
External Interrupt0 ~ 7 occurred
NOTE)
1.
Do not use the “direct bit test and branch” instruction for input port. More detail information is at chapter
17.2 Instructions on how to use the input port.
Example) Avoid direct input port bit test and branch condition as below
if(FLAG0)
→
if(EIFLAG0 & 0x01)
