Section 19 Power-Down Modes
19.8
Output of the 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 clock stops at the end of the bus cycle,
and output goes high. clock output is enabled when the PSTOP bit is cleared to 0. When DDR
for the corresponding port is cleared to 0, clock output is disabled and input port mode is set.
Table 19.5 shows the state of the pin in each processing state.
