PRNinitialVal0-1 registers

The initial value for the two RTCA-SC159 capable satellites channels should be written to the

PRNinitialVal0-1 registers. The value can be found in the RTCA-SC159 Specification.

Note: The value written to the register is the Initial Value defined by RTCA-SC159 for the PRN

required. The conversion from ‘big-endian’ as used in the specification to ‘little-endian’ as conven-

tionally used in ST20 architectures has been implemented in the hardware.

If uninitialized by the software, this register defaults to 11 1111 1111 (#3FF) as required for GPS

satellites.
