- HCS12 limitation because of HCS12 specification.
Num
Column Restriction:
- CC limitation by the Communication Controller but complies to HCS12.
{ .. } - values in ns if the CC_CLK = 40 MHz
If the parameter is not met then ECLK signal deassertion cannot be sampled and the write/read window cannot be calculated.
(X)Addr and LSTRB are taken over by the controller with the rising edge of the ECLK.
