Related data
Width selection for the phase error (E) detection function used to determine the PLL
locked/unlocked state. When a phase error greater than the E detection width from the
table occurs, the PLL circuit is seen as in the unlocked state. When unlocked, the
detection pin (DO or I/O-5) goes to the low state.

UL0, UL1
Crystal oscillator selection data
*
: After the power-on reset, 10.25 MHz is selected.
Crystal oscillator buffer (XBUF) output control data
XB = 0: Buffer output is turned off. (This mode is selected after the power-on reset.)
XB = 1: Buffer output is turned on.

Controls the phase comparator dead band.
*
: The phase comparator operates in DZA mode after the power-on reset.

Phase comparator control data
DZ0, DZ1
Bit that forcible sets the charge pump output to the low level.
DLC = 1: Low level
DLC = 0: Normal operation
*
: If a deadlock occurs due to the VCO control voltage (Vtune) going to zero and stopping
the VCO oscillator, set the charge pump output to the low level and set Vtune to V
CC
to
escape from the deadlocked state. Normal operation is selected after the power-on reset.

Charge pump control data
DLC
IC test control data
These bits must be set as follows during normal operation.
TEST0 = 0
TEST1 = 0
TEST2 = 0
*
: After the power-on reset, the test data is all set to zero.
