Memory map/register definition
21.3.30 TCD Beginning Minor Loop Link, Major Loop Count (Channel
If the TCDn_BITER[ELINK] bit is set, the TCDn_BITER register is defined as follows.
Addresses: 4000_8000h base + 101Eh offset + (32d × n), where n = 0d to 15d

Enable an interrupt when major iteration count completes
If this flag is set, the channel generates an interrupt request by setting the appropriate bit in the INT when
the current major iteration count reaches zero.

Channel Start
If this flag is set, the channel is requesting service. The eDMA hardware automatically clears this flag after
the channel begins execution.

Enables channel-to-channel linking on minor loop complete
As the channel completes the minor loop, this flag enables the linking to another channel, defined by
BITER[LINKCH]. The link target channel initiates a channel service request via an internal mechanism
that sets the TCDn_CSR[START] bit of the specified channel. If channel linking disables, the BITER value
extends to 15 bits in place of a link channel number. If the major loop is exhausted, this link mechanism is
suppressed in favor of the MAJORELINK channel linking.
NOTE: When the software loads the TCD, this field must be set equal to the corresponding CITER field.

Otherwise, a configuration error is reported. As the major iteration count is exhausted, the
contents of this field is reloaded into the CITER field.
