BLKCON2 is a special function register (SFR) to make even more reducing current consumption by turning unused
peripherals off.
[Description of Bits]
DI2C0 (bit 7)
The DI2C0 bit is used to control I2C bus interface operation. When the DI2C0 bit is set to “1”, the circuits related to
I2C bus interface are reset and turned off.
DI2C0
Description
0
Enable operating I2C (initial value)
1
Disable operating I2C
DUA0 (bit 2)
The DUA0 bit is used to control UART operation. When the DUA0 bit is set to “1”, the circuits related to UART are
reset and turned off.
DUA0
Description
0
Enable operating UART (initial value)
1
Disable operating UART
DSIO0 (bit 0)
The DSIO0 bit is used to control SSIO operation. When the DSIO0 bit is set to “1”, the circuits related to SSIO are
reset and turned off.
DSIO0
Description
0
Enable operating SSIO (initial value)
1
Disable operating SSIO
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 15, “I2C Bus Interface” for detail about operation of I2C Bus Interface.
See Chapter 14, “UART” for detail about operation of UART.
See Chapter 13, “Synchronous Serial Port” for detail about operation of SSIO.
