13.2 Bit Search Module Registers
13.2 Bit Search Module Registers
The bit search module uses the following four registers:
• 0-detection data register (BSD0)
• 1-detection data register (BSD1)
• Change-point detection data register (BSDC)
• Detection result register (BSRR)
■ 0-Detection Data Register (BSD0)
The module detects 0 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).
■ 1-Detection Data Register (BSD1)
Use a 32-bit data transfer instruction for data transfer (do not use 8-bit and 16-bit data transfer
instructions).
❍ Write
