BLKCON4 is a special function register (SFR) to make even more reducing current consumption by turning unused
peripherals off.
[Description of Bits]
Initial value
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. Only during HALT mode, When the DXTSP
bit is set to “1”, the circuits related to 32kHz oscillation stop detect are reset and turned off. When the operating mode
is not in HALT, the 32kHz oscillation stop detect is always working regardless the condition of this bit.
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.
