2MSNUM[0–4] is the sub-block code of the peripheral controller using SDMA; MSNUM[5] indicates which section,
transmit or receive, is active during the transfer. See Section19.2.4, “SDMA Transfer Error MSNUM Registers
(PDTEM and LDTEM).”
3.25µm (HiP4) devices only: available only when the primary option for this function is not used.
