This pin is shared between the P0.1 GPIO use and the CLKOUT pin. When CLK output is set, the internally selected clock is sent out onto P0.1CLKOUT pin.

The use of the pin as the P0.1 GPIO is available in all the enCoRe II parts. Bit 7: CLK Output

0 = The clock output is disabled.

1 = The clock selected by the CLK Select field (Bit [1:0] of the CLKIOCR Register (Table 10-7on page 26) is driven out to the pin.
