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.
