same time or after the change of WE to low level, the I/O pins will remain high impedance state. 3. When WE is at low level, the I/O pins are always high impedance. When WE is at high level, read operation is executed. Therefore OE should be at high level to make the I/O pins high impedance. 13 PD431000A

This issue is especially important with Schottky diodes source. This is a good assumption for low

MPU: This is the read/writecontrol signal input terminal. When R/W = “H”: Read. When R/W = “L”: Write. This is a MPU interface input pad. When connected to an 8080 series MPU, it is active LOW. This pad is connected to the RD signal of the 8080 series MPU, and the data bus is in an output status when this signal is “L”. RD When connected to a 6800 series MPU , this is active HIGH. This is used as an enable clock I (E) input of the 6800 series MPU. When RD = “H”: Enable. When RD = “L”: Disable. This

Since the C compiler assumes that constants are in RAM, rather than in program memory, when accessing the powerTab, we need to use the pgm_read_word() macro, and we need to use the powerTab as an address, i.e., precede it with "&".
