【0x10 : Interrupt factor】
Name:
INTERRUPT
Address: 0x10
Description:
This register shows the interrupt factors. Port INT outputs this register‟s OR operation.
INI : Initialization finish.
This register is set to '1 ' when initialization is complete after power-on-sequence or watch dog
timer reset. This register is cleared by setting '0 ' to the bit INI that is included the “Interrupt Source”
registers (Address 0xF0).
CAL : Software-calibration finish.
This register is set to '1 'when software calibration is complete. This register is cleared by setting
'0 ' to the bit CAL that is included the “Clear interrupt” registers (Address 0xF0).
ERCAL :Error.
This register is set to '1 'when IC should be executing the re-calibration. This register is cleared
by setting '0 ' to the bit ERCAL that is included the “Clear interrupt” registers (Address 0xF0). IC
executes self calibration after this interrupt.
PWM : PWM continuous flashing of LED finish.
This register is set to '1 'when LED PWM drive has finished. This register is cleared by clearing
every bit of the “Interrupt of PWM continuous flashing” register.
PERCAL : Periodic calibration finish.
This register is set to '1 'when periodic calibration is complete. This register is cleared by setting
'0 ' to the bit PERCAL that is included the “Clear interrupt” registers (Address 0xF0).
ONDET : Detection of switch-on.
This register is set to '1 'when it detects a switch operation is considered to be Off. This register is
cleared by clearing every bit of the “Detection Switch-On” register.
OFFDET : Detection of switch-off.
This register is set to '1 'when it detects a switch operation is considered to be Off. This register is
cleared by clearing every bit of the “Detection Switch-Off” register.
CONTDET : Detection of continued touch.
This register is set to '1 'when it detects a continued touch switch operation. This register is
cleared by clearing every bit of the “Detection continued touch” register.
