31-16 RESERVED R X

Software should not rely on the value of a reserved. Writing any

other value than the reset value may result in undefined behavior.

15-0 VALUE_INC R/W X

WCLK counter modification: Adds the written value to the running

WCLK counter. If a positive edge of WCLK occurs at the same time

as the operation, this will be taken into account. This operation is

typically used to adjust the WCLK counter after receiving the first

WASP beacon. To add a negative value, write "STMPWPER.VALUE

- value".
