9 / 38 page  EM78M612 Universal Serial Bus Microcontroller Series This specification may change without further notice. 2004/4/28 V1.1 9 8.2.1 Special Purpose Registers When the microcontroller executes instruction, specific registers are invoked for assistance, such as; Status Register which records the calculation status, Port I/O Control Registers which control the I/O pins’ direction, etc. The EM78M612 series provides a lot more of other special purpose registers with different functions. There are 23 Special Operation Registers which are located from Address 0x00 to 0x0E in Bank0, and from Address 0x08 to 0x0F in Bank1. On other hand, 17 more Special Control Registers are available to control functions or I/O direction. These are arranged from Address 0x05 to 0x0F in Bank0, and from Address 0x08 to 0x0F in Bank1. Note that Special Control Registers can only be read or written by two instructions; IOR and IOW. To access registers from Bank1, the Special Purpose Registers Bank selector (R3[7]) should be set first.
