DMAMUX channels list

Until now in all Kinetis samples i found the DMAMUX source channels were numbers, like

 

 

DMAMUX_CHCFG0 = DMAMUX_CHCFG_SOURCE(15) ;  //I2S0 Transmit
DMAMUX_CHCFG0 = DMAMUX_CHCFG_SOURCE(35) ;// FTM2_CH1  trigger - CH1 is used only to generate the DMA request

 

Were can i find a complete list, like

 

    DMAMUX_SRC_UART0_RX   = 2,
    DMAMUX_SRC_UART0_TX   = 3,
    DMAMUX_SRC_UART1_RX   = 4,
    DMAMUX_SRC_UART1_TX   = 5,
    DMAMUX_SRC_UART2_RX   = 6,
    DMAMUX_SRC_UART2_TX   = 7,
    DMAMUX_SRC_UART3_RX   = 8,
    DMAMUX_SRC_UART3_TX   = 9,
    DMAMUX_SRC_UART4_RX   = 10,
    DMAMUX_SRC_UART4_TX   = 11,

 

The reference manual says: Can be found somewhere else.

Or somebody can explain the rules how to determine those numbers.

Currently i want to put timer capture results into a cyclic buffer on the KL05.
