SUBCUD
(13) Watch error correction register (SUBCUD)
Symbol
Remark If a correctable range is –63.1 ppm or lower and 63.1 ppm or higher, set 0 to DEV.
This register is used to correct the watch with high accuracy when it is slow or fast by changing the value that
overflows from the sub-count register (RSUBC) to the second count register (reference value: 7FFFH).
SUBCUD can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
The range of value that can be corrected by using the watch error correction register (SUBCUD) is shown below.
Writing to the SUBCUD register at the following timing is prohibited.
When (F6, F5, F4, F3, F2, F1, F0) = (*, 0, 0, 0, 0, 0, *), the watch error is not corrected. * is 0 or 1.
/F5 to /F0 are the inverted values of the corresponding bits (000011 when 111100).
Range of correction value: (when F6 = 0) 2, 4, 6, 8, … , 120, 122, 124
Correctable range

• When DEV = 0 is set: For a period of SEC = 00H, 20H, 40H
• When DEV = 1 is set: For a period of SEC = 00H

Corrects watch error when the second digits are at 00, 20, or 40 (every 20 seconds).
Corrects watch error only when the second digits are at 00 (every 60 seconds).
Increases by {(F5, F4, F3, F2, F1, F0) – 1} × 2.
Decreases by {(/F5, /F4, /F3, /F2, /F1, /F0) + 1} × 2.
