MCF51EM256CLL Frequently Asked Questions (FAQ)
-
The maximum clock frequency of the MCF51EM256CLL is 50 MHz.
-
The clock source for the MCF51EM256CLL can be configured using the SYNR and REFS bits in the System Options Register (SOR). The clock source can be set to either the internal oscillator, external oscillator, or the PLL clock.
-
The LVD module in the MCF51EM256CLL is used to detect when the voltage supply falls below a certain threshold, and can be used to reset the device or generate an interrupt to alert the system of a low-voltage condition.
-
The DMA controller in the MCF51EM256CLL can be used to transfer data between peripherals and memory without CPU intervention. The DMA controller is configured using the DMA Control Register (DMACR) and the DMA Request Register (DMARQ).
-
The MCF51EM256CLL has 256 KB of flash memory, and the maximum amount of flash memory that can be programmed is 256 KB - 4 KB (reserved for the bootloader) = 252 KB.
