BLKCON1 is a special function register (SFR) to make even more reducing current consumption by turning unused
peripherals off.
[Description of Bits]
Note:
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.
See Chapter 8, “1kHz Timer” for detail about operation of 1kHz Timer.
See Chapter 10, “PWM” for detail about operation of PWM.

BLKCON1
The DT1K bit is used to control 1kHz Timer operation. When the DT1K bit is set to “1”, the circuits related to 1kHz
Timer are reset and turned off.
The DPW2 bit is used to control PWM2 operation. When the DPW2 bit is set to “1”, the circuits related to PWM2
are reset and turned off.
The DPW1 bit is used to control PWM1 operation. When the DPW1 bit is set to “1”, the circuits related to PWM1
are reset and turned off.
The DPW0 bit is used to control PWM0 operation. When the DPW0 bit is set to “1”, the circuits related to PWM0
are reset and turned off.
