21.8
Output of the ø 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 ø clock stops at the end of the bus cycle, and ø output goes high. ø clock output is
enabled when the PSTOP bit is cleared to 0. When DDR for the corresponding port is cleared to 0, ø clock output is
disabled and input port mode is set. Table 21-5 shows the state of the ø pin in each processing state.
