4590B–4BMCU–02/03
Figure 11. RAM Map
Registers The microcontroller has seven programmable registers and one condition code register
(see Figure 12).
Program Counter (PC) The program counter is a 12-bit register which contains the address of the next instruc-
tion to be fetched from the EEPROM. Instructions currently being executed are decoded
in the instruction decoder to determine the internal micro-operations. For linear code (no
calls or branches), the program counter is incremented with every instruction cycle. If a
branch-, call-, return-instruction or an interrupt is executed, the program counter is
loaded with a new address. The program counter is also used with the table instruction
to fetch 8-bit wide EEPROM constants.
