2.9.1
The BSET, BCLR, BNOT, BST, and BIST instructions are used to read data in byte-wise, operate
the data in bit-wise, and write the result of the bit-wise operation in bit-wise again. Therefore,
special care is necessary to use these instructions for the registers and the ports that include write-
only bit.
The BCLR instruction can be used to clear the flags in the internal I/O registers to 0. In this time,
if it is obvious that the flag has been set to 1 in the interrupt handler, there is no need to read the
flag beforehand.

Notes: 1. From any state except hardware standby mode, a transition to the reset state occurs whenever RES goes low.
2. In every state, when the STBY pin becomes low, the hardware standby mode is entered.
3. For details, refer to section 22, Power-Down Modes.
Usage Note

A transition can also be made to the reset state when the watchdog timer overflows.
