CHAPTER 13 BIT SEARCH MODULE
❍
Read
Data saved for the internal status of the bit search module is read from this register. When the
interrupt handler uses the bit search module, the register is used to save the current status and
restore it. Even when data is written to the 0-detection or change-point detection data register, the
original data can be saved and restored only by using the 1-detection data register.
The initial value after resetting is undefined.
■
Change-Point Detection Data Register (BSDC)
The module detects a change point for the value written to this register.
The initial value after resetting is undefined.
The value read from this register is undefined.
Use a 32-bit data transfer instruction for data transfer (do not use 8-bit and 16-bit data transfer
instructions).
■
Detection Result Register (BSRR)
The result of 0-detection, 1-detection or change-point detection is read from this register.
The type of the detection result that is read from this register is determined by the data register
written last.
