Clocking

The following steps describe how to use Table 74. See Example 1.

1. Choose the up or down sections in the table according to input clock rate 33 MHz or 66 MHz.

2. Select a suitable CSB and core clock rates from Table 74. Copy the SPMF and CORE PLL

configuration bits.

3. Select a suitable QUICC Engine block clock rate from Table 74. Copy the CEPMF and CEPDF

configuration bits.

4. Insert the chosen SPMF, COREPLL, CEPMF and CEPDF to the RCWL fields, respectively.

1 The Conf No. consist of prefix, an index and a postfix. The prefix “s” and “c” stands for “syset” and “ce” respectively. The postfix

“h” stands for “high input clock.’”The index is a serial number.
