SOFTWARE RESET AND CHIP ID

A Software Reset can be commanded by writing to Register R15. This is a read-only register field and

the contents will not be affected by writing to this Register. Note that the PLL Registers (R114 through

to R152) are not affected by this Software Reset; these registers can be reset separately.

A PLL Software Reset can be commanded by writing to Register R127. This is a read-only register

field and the contents will not be affected by writing to this Register. The PLL Software Reset causes

the contents of the PLL Registers (R114 through to R152) to be reset to their default states.

The Customer ID and Chip Revision ID can be read back from Register R1 (01h), as described in

Table 132.
