Eight Different Values Programming Possibility in CY22394

Question: It is possible in the CY22394 to select eight different values of the frequency of PLL 1 using the start-up values of S0, S1 and S2. However, is it possible to program them to flash using software?



Currently the software only allows two table entries to be used on the CY22394, switchable with the S2 pin. The first four table entries are set to the S2=0 setting, and the second four are all set to the S2=1 setting. Therefore, the S0 and S1 pins can be in any state at power up.

The CY22392 will allow for all 8-table entries to be used but it does not have an I2C interface.
