【0xD0 – 0xD6 : Mask switch operation】
Name:
MSK_SW_KEY
Address: 0xD0 - 0xD6
Description: This register is for mask to the operation of each matrix switches and each simple switches. The masked
switches are excluded from the interrupt factor. It is prohibited that one sensor is assigned to both a matrix
switch and a simple switch. The unused switches must be masked. The switches configured by the not
included sensors in IC (SIN10-15 in BU21072MUV, SIN8-10 and SIN15 in BU21078MUV/BU21078FV)
must be masked.
1 : Masked. 0 : Unmasked.

【0xDF : Mask interrupt】
Name:
MSK_INTERRUPT
Address: 0xDF
Description: This register is for mask to the interrupt factor. The masked interrupt factor is not shown on the register
"Interrupt factor (address 0x10)", so it does not affect to output port INT.
1 : Masked. 0 : Unmasked.
MSK_CAL : Mask for Software-calibration finish.
This bit does mask to the interrupt of Software-calibration finish (the bit CAL in the register
INTERRUPT(address 0x10)).
MSK_ERCAL : Mask for Self-calibration finish.
This bit does mask to the interrupt of Self-calibration finish (the bit ERCAL in the register
INTERRUPT(address 0x10)).
MSK_PERCAL : Mask for Periodic calibration finish.
This bit does mask to the interrupt of Periodic calibration finish (the bit PERCAL in the register
INTERRUPT(address 0x10)).
