BU21170MUV
【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 ‘Clear interrupt’ 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 : Self-re-calibration finish :
This register is set to ‘1’ when self-re-calibration is complete. Self-re-calibration runs automatically
after the detection that IC should be re-calibration. This register is cleared by setting ‘0’ to the bit
ERCAL that is included the ‘Clear interrupt’ registers (Address 0xF0).
PWM : PWM continuous flashing of LED finish :
This register is set to ‘1’ when LED’s 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 On. 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 continuous touch’ register.
