Section 21 Power-Down Modes
21.7
The 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 21.4 shows the state of the pin in each processing state.
