3.11.2 PLL Configuration

After POR, warm reset, and max reset, the PLLs and clocks are set to their default configurations. The PLLs are in bypass mode and disabled by default. This means that the input reference clock at MXI1 (typically 24 MHz) drives the chip after reset. For more information on device clocking, see Section 3.5 and Section 3.6. The default state of the PLLs is reflected in the default state of the register bits in the PLLC registers. Refer the the ARM Subsystem User'sGuide for PLLC register descriptions.

3.11.3 Power Domain and Module State Configuration

Only a subset of modules are enabled after reset by default. Table 3-16shows which modules are enabled after reset. Table 3-16as shows that the following modules are enabled depending on the sampled state of the device configuration pins: EDMA (CC and TC0), AEMIF, MMC/SD0, UART0, and Timer0. For example, UART0 is enabled after reset when the device configuration pins (BTSEL[1:0] = 11 - Enable UART) select UART boot mode. For more information on module configuration refer to the ARM
