The Block Init Register is a 32 bit read/write register at address 040288 - 04028B
The Block Init Register is used during block initialization of the connection memory. A block initialization
automatically occurs at power-up. However, it is possible to perform a block initialization at any time. During Block
Initialization, the value of the Block Init Register is copied to all connection memory locations in an operation that
runs in about 120 µs. If the Block Init Register is modified during a block initialization, the new value used is
ignored.

Clock Polarity Selection for CKo0
When this bit is low, CKo0 is set for the positive clock edge.
When this bit is high, CKo0 is set for the negative clock edge.
Output Clock Rate for CKo0 and FPo0
The output clock rate can not exceed the selected clock source rate. All rates are avail-
able when the internal system clock is selected as clock source.
