be put into its Standby mode (LRSTDBY) to reduce the power utilization of that regulator.
All peripherals, except the COP/watchdog timer, run at the system clock (peripheral bus) frequency1,
which is the same as the main processor frequency in this architecture. The COP timer runs at
MSTR_OSC / 1024. The maximum frequency of operation is SYS_CLK = 32MHz. The only exception is
the Quad Timer and PWM, which can be configured to operate at three times the system bus rate using
TCR and PCR controls, provided the PLL is active and selected.
6.6 Resets
The SIM supports four sources of reset, as shown in Figure 6-15. The two asynchronous sources are the
external reset pin and the Power-On Reset (POR). The two synchronous sources are the software reset,
which is generated within the SIM itself by writing the SIM_CTRL register in Section 6.3.1, and the COP
reset. The SIM uses these to generate resets for the internal logic. These are outlined in Table 6-4. The
first column lists the four primary resets which are calculated. The JTAG circuitry is reset by the Power-On
Reset. Columns two through five indicate which reset sources trigger these reset signals. The last column
provides additional detail.
Figure 6-15 provides a graphic illustration of the details in Table 6-4. Note that the POR_Delay blocks
use the Relaxation Oscillator Clock as their time base since other system clocks are inactive during this
phase of reset.
1. The Quad Timer and PWM modules can be operated at three times the IPBus clock frequency.
