Y4/Y8 bits of the unlock port ( φ K27) become unfixed.
Note:
The phase comparator control port and the unlock detection ports are accessed by using the OUT2 instruction with [CN =
4H, 5H, 6H, 7H] and the IN2 instruction with [CN = 7H] specified in the operand. These control bits are reset to "0" after a
system reset.
Output mode setting (M0 and M1 bits)
The M0 and M1 bits are used for setting the phase comparator output (DO1/2 output pin) state. The phase
comparator output, the "H" and "L" levels and high impedance (HZ) state can be set.
Note:
If the PLL off mode is selected, the "HZ" will be retained in the phase comparator output state,
and the "H"/"L" level will be retained when the "H"/"L" level is selected.
When PN = "1" is selected, the PN output mode has the priority.
Note:
Output resistance setting (R0 and R1 bits)
The R0 and R1 bits are used for setting the output resistance of the phase comparator output individually for DO1
and DO2 pins. They can be set to four states; the normal output buffer state, 5 kΩ, 50 kΩ and 100 k Ω .
Note:
The output resistance is set regardless of the output mode (M0, M1) and the PN output mode.
Therefore, set these bits to "0" when the "H"/"L" level or the PN output mode is selected.
Note:
When the DO2 pin is set to the automatic phase difference switching mode, the R0/R1 bits of
DO2 control 1 becomes to the "don't care" state.
