MCU Control Function

4.3.4
Block Control Function
This LSI has a block control function, which resets and completely turns operating circuits of unused peripherals off to
make even more reducing current consumption.
When certain bits of block control registers are set to “1”, corresponding peripherals are reset (all registers are reset)
and operating clocks for the peripherals stop. Writing to every SFR (special function register) in the corresponding
peripherals is not valid while the bits of block control registers are set to “1” and returns the initial value for read.
Ensure the bits are reset to “0” before using the peripherals to enable the operation.
BLKCON0 register controls(disables/enables) operation of Timer 0, Timer 1, Timer 2 and Timer 3.
BLKCON1 register controls(disables/enables) operation of Capture, 1kHz Timer and PWM.
BLKCON2 register controls(disables/enables) operation of I2C, UART and SSIO.
BLKCON3 register controls(disables/enables) operation of Melody/Buzzer.
BLKCON4 register controls(disables/enables) operation of LCD driver, Battery Level Detector, 32kHz oscillation stop
detector, RC type A/D converter and SAR type A/D converter.
Note:
DXTSP bit (bit 4) of BLKCON4 register disables the operation of 32kHz oscillation stop detector in HALT mode only.
See the each chapter for detail about the opeation of each peripheral and relevant notes.
* ML610Q411PA has a different specification of that the circuits related to 32kHz oscillation stop detect are reset and
turned off (disabled) when the DXTSP bit is set to “1” regardless the CPU in HALT mode or not.
