Reset Operation
Before resetting the TMPA901CM, make sure that the power supply voltage is within the
When the TMPA901CM is reset, the PLL stops, the PLL output is unselected, and the
The system clock therefore operates at 25 MHz (X1 = 25 MHz).
If the reset instruction is accepted, the built-in I/O, I/O ports and other pins are
