12. EXTERNAL INTERRUPTS  
The external interrupt pins are edge triggered depending on the „external interrupt registers.  
The edge detection of external interrupt has three transition activated mode: rising edge, falling edge,  
and both edge.  
12.1 Registers  
EINT0H EXT 2~5 / R04~R07  
R0 PORT EXTERNAL INTERRUPT ENABLE HIGH REGISTER  
00CAH  
A reset clears the EINT0H register to 00H, disables EXT5-EXT2 interrupt. You can use EINT0H  
register setting to select Disable interrupt or Enable interrupt (by falling, rising, or both falling and  
rising edge).
