â Transfers the contents of register A to key-on wakeup control register K1.
â
â Transfers the contents of key-on wakeup control register K2 to register A.
â
â Transfers the contents of register A to key-on wakeup control register K2.
â
â Transferts the contents of register A to port output format control register FR0.
â
â Transferts the contents of register A to port output format control register FR1.
â
â Transferts the contents of register A to port output format control register FR2.
â
â Transfers the high-order 4 bits of serial I/O register SI to register B, and transfers the low-order 4 bits of se-
rial I/O register SI to register A.
