19. Power-Down State
MSTCR Access from DMAC Disabled: To prevent malfunctions, MSTCR can only be accessed
from the CPU. It can be read by the DMAC, but it cannot be written by the DMAC.
19.7
Output of the system clock (φ) can be controlled by the PSTOP bit in MSTCRH. When the
PSTOP bit is set to 1, output of the system clock halts and the φ pin is placed in the high-
impedance state. Figure 19.3 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 19.4 indicates
the state of the φ pin in various operating states.
