Module "SM1"       (bean SynchroMaster)
   - SM1_RecvChar -If any data is received, this method returns one character, otherwise it returns an error code (it does not 
                wait for data). Version specific information for Freescale 56800 derivatives ]   DMA mode:  If DMA controller 
                is available on selected CPU and receiver is configured to use DMA controller then this method only sets the 
                selected DMA channel. Status of the DMA transfer can then be checked using method GetCharsInRxBuf. See typical 
                usage for details about communication using DMA.
   - SM1_SendChar -Sends one character to the channel. Version specific information for Freescale 56800 derivatives ]   DMA 
                mode:  If DMA controller is available on the selected CPU and the transmitter is configured to use DMA 
                controller then this method only sets the selected DMA channel. The status of the DMA transfer can then be 
                checked using GetCharsInTxBuf method. See the typical usage for details about communication using DMA.
   - SM1_GetCharsInRxBuf -Returns the number of characters in the input buffer.  Note: If the Interrupt service is disabled, 
                and the Ignore empty character is set to yes, and a character has been received, then this method returns 1 
                although it was an empty character. Version specific information for Freescale 56800 derivatives ]   DMA mode:  
                If DMA controller is available on the selected CPU and the receiver is configured to use DMA controller then 
                this method returns the number of characters in the receive buffer.
   - SM1_GetCharsInTxBuf -Returns the number of characters in the output buffer. Version specific information for Freescale 
                56800 derivatives ]   DMA mode:  If DMA controller is available on the selected CPU and the transmitter is 
                configured to use DMA controller then this method returns the number of characters in the transmit buffer.
   - SM1_GetError -Returns a set of errors on the channel (errors that cannot be returned in given methods). The errors 
                accumulate in a set; after calling [GetError] this set is returned and cleared.

Module "Cpu"       (bean MC9S12DP256_112)
   - Cpu_EnableInt -Enable maskable interrupts
   - Cpu_DisableInt -Disable maskable interrupts
   - Cpu_SetWaitMode -Set low power mode - Wait mode.  For more information about the wait mode see documentation of this CPU.  
                Release from Wait mode: Reset or interrupt
   - Cpu_SetStopMode -Set low power mode - Stop mode.  For more information about the stop mode see documentation of this CPU.
