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.
