Suppose the Vole communicates with a printer using the technique of memory-mapped I/O. Suppose also that address 0xFF is used to send characters to the printer, and address 0xFE is used to receive information about the printer’s status. In particular, suppose the least significant bit at the address 0xFE indicates whether the printer is ready to receive another character (with a 0 indicating “not ready” and a 1 indicating “ready”). Starting at address 0x00, write a machine language routine that waits until the printer is ready for another character and then sends the character represented by the bit pattern in register 0x5 to the printer.
