> ## Appendix B.

> ### B.1 Default Values for all the Peripheral Control Registers

> The default values for all of the peripheral control registers are shown in this appendix. The registers within the CPU affected by reset are the Stack Pointer (SP), the Program Counter (PC), the IIR register, the EIR register, and the IP register. The IP register is set to all ones (disabling all interrupts), while all of the other listed CPU registers are reset to all zeros.
