Section 2 CPU
As a result of this operation, bit 0 in PCR3 becomes 0, making P3
and 6 in PCR3 change to 1, so that P3
To avoid this problem, store a copy of the PCR3 data in a work area in memory. Perform the bit
manipulation on the data in the work area, then write this data to PCR3.
[A: Prior to executing BCLR]
[B: BCLR instruction executed]
[C: After executing BCLR]

The PCR3 value (H'3F) is written to a work area in
memory (RAM0) as well as to PCR3.
The BCLR instruction is executed designating the PCR3
work area (RAM0).
