12.8 Fixed Period Clock Output Function
When using SIO0, SIO1, SIO4 or SIO5 in UART mode, the relevant port (P84, P87, P65 or P66) can be switched
for use as an SCLKO0, SCLKO1, SCLKO4 or SCLKO5 pin, respectively. That way, a BRG output clock divided by
2 can be output from the SCLKO pin.
Note: • This clock is output not just during data transfer.
