/*!
* brief eDMA IRQ handler for the current major loop transfer completion.
*
* This function clears the channel major interrupt flag and calls
* the callback function if it is not NULL.
*
* Note:
* For the case using TCD queue, when the major iteration count is exhausted, additional operations are performed.
* These include the final address adjustments and reloading of the BITER field into the CITER.
* Assertion of an optional interrupt request also occurs at this time, as does a possible fetch of a new TCD from
* memory using the scatter/gather address pointer included in the descriptor (if scatter/gather is enabled).
*
* For instance, when the time interrupt of TCD[0] happens, the TCD[1] has already been loaded into the eDMA engine.
* As sga and sga_index are calculated based on the DLAST_SGA bitfield lies in the TCD_CSR register, the sga_index
* in this case should be 2 (DLAST_SGA of TCD[1] stores the address of TCD[2]). Thus, the "tcdUsed" updated should be
* (tcdUsed - 2U) which indicates the number of TCDs can be loaded in the memory pool (because TCD[0] and TCD[1] have
* been loaded into the eDMA engine at this point already.).
*
* For the last two continuous ISRs in a scatter/gather process, they both load the last TCD (The last ISR does not
* load a new TCD) from the memory pool to the eDMA engine when major loop completes.
* Therefore, ensure that the header and tcdUsed updated are identical for them.
* tcdUsed are both 0 in this case as no TCD to be loaded.
*
* See the "eDMA basic data flow" in the eDMA Functional description section of the Reference Manual for
* further details.
*
* param handle eDMA handle pointer.
