Bit band region
WebThe provided macros, HWREGBITW etc, "hide" the bit-band regions to the programmer such that the programmer only needs to program which bit of a register (in the bit-band alias region) he wants to write or read. Thus the macro maps the register and bit number to an address in the bit-band region and then the bus performs the bit-band operation ... WebBit-banding maps a complete word of memory onto a single bit in the bit-band region. For example, writing to one of the alias words will set or clear the corresponding bit in the …

WebMar 12, 2013 · We can infer from this that HWREG takes some sort of address in some form. This will help us work out what HWREGBITB does. HWREGBITB (x, b) takes it's x value, ( ( (unsigned long) (x) & 0xF0000000) ): Clears out all the bits except the most significant 4 bits (assuming longs are 32 bits wide) ( 0x02000000 ): Sets the next 4 bits … WebSo they use part of it for what's called bit banding.
