Not used
Interrupt valid waveform for INT0 pin/
return level selection bit (Note 2)
INT0 pin edge detection circuit control bit
INT0 pin
timer 1 control enable bit
This bit has no function, but read/write is enabled.
Falling waveform (“L” level of INT1 pin is recognized with the SNZI1
instruction)/“L” level
Rising waveform (“H” level of INT1 pin is recognized with the SNZI1
instruction)/“H” level
One-sided edge detected
Both edges detected
Disabled
Enabled
Not used
Interrupt valid waveform for INT1 pin/
return level selection bit (Note 3)
INT1 pin edge detection circuit control bit
INT1 pin
timer 3 control enable bit
Notes 1: “R” represents read enabled, and “W” represents write enabled.
2: When the contents of I12 is changed, the external interrupt request flag EXF0 may be set. Accordingly, clear EXF0 flag with the SNZ0 instruction.
3: When the contents of I22 is changed, the external interrupt request flag EXF1 may be set. Accordingly, clear EXF1 flag with the SNZ1 instruction.
