Chapter 4 MCU Control Function
4.3.5
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.
For each block control register, the initial value of each flag is "0", meaning the operation of each block is enabled. When
any flag is set to "1" (Disable Operating), the function of the applicable block is reset and the clock supply to this block is
stopped. When this flag is set to "1", the writing to all registers in the applicable block becomes invalid, and thus the
reading from such register becomes the initial value. When using the function of the applicable block, ensure to reset the
applicable flag of this block control register to "0" (enable operation).
・ BLKCON0 register: Controls (enables/disables) the operation of the Timers 0, 1, 2, and 3 circuits.
・ BLKCON1 register: Controls (enables/disables) the operation of the PWM0 and capture circuits.
・ BLKCON2 register: Controls (enables/disables) the operation of the UART0, SSIO0, and SSIO1 circuits.
・ BLKCON3 register: Controls (disables/enables) the operation of the melody driver 0 circuit.
・ BLKCON4 register: Controls (disables/enables) the operation of the LCD driver and RC oscillation type A/D
converter circuits.
