"WebThe Microchip mid-range PIC microcontrollers use a sequence known as Read-Modify-Write (RMW) when changing an output state (1 or 0) on a pin. This can cause unexpected behavior under certain circumstances. When your program changes the state on a specific pin, for example RB0 in PORTB, the PIC microcontroller first READs all 8 bits of the PORTB ... " - Readmodify-write

In computer science, read–modify–write is a class of atomic operations (such as test-and-set, fetch-and-add, and compare-and-swap) that both read a memory location and write a new value into it simultaneously, either with a completely new value or some function of the previous value. These operations prevent race conditions in multi-threaded applications. Typically they are used to implement mutexes or semaphores. These atomic operations are also heavily used in non-blockin… WebNov 6, 2024 · DDR5, with its high data rate, is expected to possess as large as 43% of the global DRAM market share by 2024, according to SK Hynix.
