    Description

    Start the PLL. Before the start, the system was operated with the crystal oscillator or clock input.

    After PLL enabled for 100us, can start to lock PLL

    0 Use reference clock as system clock

    1 Use PLL output as system clock

    A[0] : Enable PLL (POR = 0)

    0 Disable PLL

    1 Enable PLL

    Before enabling PLL, the PLL setting (“0xE2”) have to be configured first. After PLL enabled for 100us, can start to

    lock PLL. SSD1963 needed to switch to PLL output as system clock after PLL is locked. The following is the program

    sequence.

    Wait 100us to let the PLL stable

    * Note : SSD1963 is operating under reference clock before PLL is locked, registers cannot be set faster than half of the

    reference clock frequency. For instance, SSD1963 with a 10MHz reference clock is not allowed to be programmed

    higher than 5M words/s.
