The quiescent current of 9S12ZVL in STOP mode

Hi, I used MC9S12ZVL32 in my application and I have a problem.
1. I am using an internal 1 MHz RC oscillator
2. When I set the internal bus clock to 16mhz and MC9S12ZVL32 enters stop mode, the Isup current is 1.2mA.
3. When I set the internal bus clock to 2mhz and the MC9S12ZVL32 enters stop mode, Isup is 26uA.
Why is this happening?
Is the quiescent current related to the bus clock?
