Memory-mapped registers in System Control operate on the INTOSC1 clock domain; hence, any CPU writes to these registers requires a delay between subsequent writes otherwise the second write can be lost. The application needs to take this into consideration and check the SYNCBUSY and SYNCBUSYWD status registers after every write to the registers that are mentioned in Table 3-15.
