Section 21 Power-Down State
21.7
Output of the system clock ( ) can be controlled by the PSTOP bit in MSTCR. When the PSTOP
bit is set to 1, output of the system clock halts and the pin is placed in the high-impedance state.
Figure 21.3 shows the timing of the stopping and starting of system clock output. When the
PSTOP bit is cleared to 0, output of the system clock is enabled. Table 21.4 indicates the state of
the pin in various operating states.
