The control registers are the 24-bit program counter (PC) and the 8-bit condition-code register
(CCR).
(1) Program Counter (PC)
This 24-bit counter indicates the address of the next instruction the CPU will execute. The length
of all CPU instructions is 16 bits (one word) or a multiple of 16 bits, so the least significant PC bit
is ignored. When an instruction is fetched, the least significant PC bit is regarded as 0.
(2) Condition Code Register (CCR)
This 8-bit register contains internal CPU status information, including the interrupt mask bit (I)
and half-carry (H), negative (N), zero (Z), overflow (V), and carry (C) flags.
Bit 7—Interrupt Mask Bit (I): Masks interrupts other than NMI when set to 1. (NMI is accepted
regardless of the I bit setting.) The I bit is set to 1 by hardware at the start of an exception-
handling sequence.
Bit 6—User Bit (U): Can be written and read by software using the LDC, STC, ANDC, ORC, and
XORC instructions. This bit can also be used as an interrupt mask bit. For details see the relevant
microcontroller hardware manual.
