12.4.2
DCKDR is a 32-bit readable/writable register that specifies use/non-use of clock output from the
DCK pin and the DCK clock frequency division ratio.
By setting the DIV1 and DIV0 bits, the CKIO clock is divided by 1, 2, or 3 and supplied to the
DCK pin. This division ratio setting also allows the DCK clock to be extended to become one to
three CKIO cycles even while BS2 is being asserted. For details on adjustment of the CS negate
time, see the description of WCR4.

Reserved
These bits are always read as 0. The write value
should always be 0.
PLL Circuit 3 Enable
Specifies whether PLL circuit 3 is on or off.
Writing 1 to this bit turns the on-chip PLL circuit 3
on.
0: PLL circuit 3 is not used. In this case, the DCK
1: PLL circuit 3 is used.
DCK Output Control
Controls the DCK pin state. Writing 1 to this bit
sets the DCK pin at the output state.
0: DCK pin goes to high-impedance state
1: Clock is output from DCK pin
Indicates whether the DCK output clock is stable
