TMS320C6678: TSIP "pending active" condition

Hi,

When a channel configuration (A or B) is active those configuration

registers are write protected. A channel configuration (A or B) that is pending active

also is write protected. Write accesses to the inactive configuration registers update the

inactive registers.

When the channel is disabled both bitmaps are inactive and can be modified. The least

significant bit of the CnID value determines which of the two channel bitmaps is made

pending and becomes active on the next superframe. A channel bitmap can be

designated as pending active at any time. When a bitmap becomes pending active, both

it and the active bitmap are protected until the pending active bitmap is made active

and the active bitmap is made inactive. Changes in the actual active assignment always

occur on a superframe.

Pending active means you will be active in the next superframe. What is current active will be inactive in the next superframe.
