4.8.11.12 MSMCR1 – Host State Machine Control Register 1

The SSM module has eight places to configure and store the host state machine run order. MSMSM0-MSMSM7 holds a maximum of eight numbers defining the sub-state machines (see the following table). Using these fields allows the definition of the exact initialization or run process in the right order. By inserting appropriate state machine numbers, it is possible to, for example, that VCO tuning must take place or not. The first entry in this series of registers that is set to ‘0’ defines the end of the configuration. The host state machine stops operation upon reaching this ‘0’ value. Undefined values for MSMSMx are treated as ‘0’ and lead to a completed state machine sequence.

Bits 7:4 – MSMSM1[3:0] Host State Machine (Sub)State Machine Select 1

This value defines the second sub-state machine that must be run by the SSM host state machine.

Bits 3:0 – MSMSM0[3:0] Host State Machine (Sub)State Machine Select 0

This value defines the first sub-state machine that must be run by the SSM host state machine. For configuration, see the following table.
