PRE_DIVN[14:8]_CNFG - DivN Divider Division Factor Configuration 2
Address: 25H
Type: Read / Write
Default Value: X0000000

Reserved.
If the value in the PRE_DIVN_VALUE[14:0] bits is plus 1, the division factor for an input clock will be gotten. The input
clock is selected by the PRE_DIV_CH_VALUE[3:0] bits (b3~0, 23H).
A value from ‘0’ to ‘4BEF’ (Hex) can be written into, corresponding to a division factor from 1 to 19440. The others are
reserved. So the DivN Divider only supports an input clock whose frequency is lower than (
<
) 155.52 MHz.
6 - 0
PRE_DIVN_VALUE[14:8]
The division factor setting should observe the following order:
1. Write the lower eight bits of the division factor to the PRE_DIVN_VALUE[7:0] bits;
2. Write the higher eight bits of the division factor to the PRE_DIVN_VALUE[14:8] bits.
