Reset
This section describes the MPC561/MPC563 reset sources, operation, control, and status.
7.1
The MPC561/MPC563 has several inputs to the reset logic which include the following:
All of these reset sources are fed into the reset controller. The control logic determines the cause of the
reset, synchronizes it, and resets the appropriate logic modules, depending on the source of the reset. The
memory controller, system protection logic, interrupt controller, and parallel I/O pins are initialized only
on hard reset. External soft reset initializes internal logic while maintaining system configuration.
The reset status register (RSR) reflects the most recent source to cause a reset.
7.1.1
The power-on reset pin, PORESET, is an active low input. In a system with power-down low-power mode,
this pin should be activated only as a result of a voltage failure on the KAPWR pin. After detecting the
assertion of PORESET, the MPC561/MPC563 enters the power-on reset state. During this state the
MODCK[1:3] signals determine the oscillator frequency, PLL multiplication factor, and the PITRTCLK
and TMBCLK clock sources. In addition, the MPC561/MPC563 asserts the SRESET and HRESET pins
at the rising edge of PORESET.
The PORESET pin should be asserted for a minimum time of 100,000 of clock oscillator cycles after a
valid level has been reached on the KAPWR supply. After detecting the assertion of PORESET, the
MPC561/MPC563 remains in the power-on reset state until the last of the following two events occurs:
