BLKCON4
The DLCD bit is used to control LCD driver operation. When the DLCD bit is set to “1”, the circuits related to LCD
driver are reset and turned off.
The DBLD bit is used to control BLD (Battery Level Detector) operation. When the DBLD bit is set to “1”, the
circuits related to BLD are reset and turned off.
The DXTSP bit is used to control 32kHz oscillation stop detect operation. When the DXTSP bit is set to “1”, the
circuits related to 32kHz oscillation stop detect are reset and turned off.
The DRAD bit is used to control RC type A/D converter operation. When the DRAD bit is set to “1”, the circuits
related to RC type A/D converter are reset and turned off.
