The SUPV bit places the SIM global registers in either supervisor or user data space.
Determines SIM interrupt arbitration priority. The reset value is $F (highest priority), to
prevent SIM interrupts from being discarded during initialization.
SIMTR is used for factory test only.
SYNCR determines system clock operating frequency and mode of operation. Clock
frequency is determined by SYNCR bit settings as follows:
The Y field is the initial value for the modulus 64 down counter in the synthesizer feed-
back loop. Values range from 0 to 63.
RESET:
0 = Registers with access controlled by the SUPV bit are accessible from either the
1 = Registers with access controlled by the SUPV bit are restricted to supervisor
0 = Internal modules are addressed from $7FF000 – $7FFFFF.
1 = Internal modules are addressed from $FFF000 – $FFFFFF.
0 = Base VCO frequency
1 = VCO frequency multiplied by four
0 = VCO frequency divided by four (base system clock frequency)
1 = VCO frequency divided by two (system clock frequency doubles)
0 = ECLK is system clock divided by 8
1 = ECLK is system clock divided by 16
0 = External crystal is VCO reference
1 = Loss of crystal reference
0 = VCO is enabled, but has not locked.
1 = VCO has locked on the desired frequency or system clock is external.
