Always reads $00.
Writing $55 to this address is the first step of the COP watchdog sequence.
Writing $AA to this address is the second step of the COP watchdog sequence. Other instructions may
be executed between these writes but both must be completed in the correct order prior to time-out to
avoid a watchdog reset. Writing anything other than $55 or $AA causes a COP reset to occur.
Read and write anytime.
The slow clock divider is included to deliver a variable clock frequency to the MCU in wait mode. This
slow clock is drived from the EXTALi and in wait mode can be used for the system clocks.
Write to this register changes the SLWCLK frequency. The frequency divide ratio is 2 times SLOW reg-
ister value, hence the divide range is 2 to 30, by steps of 2. When SLOW register = 0, the divider is
bypassed. The generation of E and P clocks further divides SLWCLK by 2. Hence, the final ratio of Bus
to EXTAL Frequency is programmable to 2, 4, 8, 12, 16, ..., 60, by steps of 4.
