Explain psw register of 8051
WebApr 13, 2024 · Two bits in the PSW register are used to select the register bank in the RAM for storing data. By default, register bank 0 stores all the data. Note: the 8051 has four register banks containing eight registers each. The PSW register is bit addressable, which allows the programmer to access each bit individually. http://www.ee.ncu.edu.tw/~jztsai/EE3046/lecture/8051%20-%20PSW.htm
