■ 1 Detection Data Register (BSD1)
Figure 11.5-3 shows the bit configuration of the 1 detection data register (BSD1).
Figure 11.5-3 Bit Configuration of the 1 Detection Data Register (BSD1)
000003F4
Read/write
Initial value
Use a 32-bit length data transfer instruction for data transfer.
Do not use 8-bit or 16-bit length data transfer instructions.
❍ Writing
1 detection is performed for the written data.
❍ Reading
Save data of the internal state of the bit search module is read. This register is used to save and
restore the original state when the bit search module is used by, for example, an interrupt
handler.
Even though data is written to the 0 detection or change point detection data register, data can be
saved and restored only by using the 1 detection data register.
The initial value after a reset is undefined.
■ Change Point Detection Data Register (BSDC)
Figure 11.5-4 shows the bit configuration of the change point detection data register (BSDC).

000003F8
Read/write
Initial value
Point of change are detected in the written value.
The initial value after a reset is undefined.
The read value is undefined.
Use a 32-bit length data transfer instruction for data transfer. Do not use 8-bit or 16-bit length
data transfer instructions.
