2.9.1
Bit manipulation instructions such as BSET, BCLR, BNOT, BST, and BIST read data in byte
units, perform bit manipulation, and write data in byte units. Thus, care must be taken when these
bit manipulation instructions are executed for a register or port including write-only bits.
In addition, the BCLR instruction can be used to clear the flag of an internal I/O register. In this
case, if the flag to be cleared has been set by an interrupt processing routine, the flag need not be
read before executing the BCLR instruction.
Notes: 1. From any state except hardware standby mode, a transition to the reset state occurs whenever
2. In every state, when the STBY pin becomes low, the hardware standby mode is entered.
3. For details, refer to section 16, Power-Down Modes.
A transition can also be made to the reset state when the watchdog timer overflows.
