Bits 1 and 0: REF30P Division Ratio Selection Bits (DVREF1, DVREF0)
Select the division value of REF30P. If it is read-accessed, the counter value is read out. (The
selected division value is set by the UDF of the counter.)

Bit :
Initial value :
R/W :
The X-value data register (XDR) is a 16-bit write-only register. No read is valid. If a read is
attempted, an undefined value is read out. XDR accepts only a word-access. If a byte access is
attempted, operation is not assured.
Set X-value correction data to XDR, except a value which is beyond the cycle of the CTL pulse.
If AT/
08 = 0, TRK/; = 0 was set, CAPREF30 can be generated only by the setting of XDR.
Set an X-value and TRK correction value in PB mode, and an X-value in REC mode.
It is initialized to H'F000 by a reset, stand-by or module stop.
