The output of the φ clock can be controlled by means of the PSTOP bit in SCKCR, and DDR for
the corresponding port. When the PSTOP bit is set to 1, the φ clock stops at the end of the bus
cycle, and φ output goes high. φ clock output is enabled when the PSTOP bit is cleared to 0. When
DDR for the corresponding port is cleared to 0, φ clock output is disabled and input port mode is
set. Table 20.4 shows the state of the φ pin in each processing state.
