14.5.4 Usage Notes when Writing to and Reading the Register
After writing to a count register such as the second counter or to the RCR2 register, perform
two dummy reads before reading from the register. The register value before the write is
returned by the two dummy reads. The value newly written to the register takes effect only on
the third read operation.
Registers other than the above can be read immediately after a write and the written value is
reflected.
