2.4.2
This 24-bit counter indicates the address of the next instruction the CPU will execute. The length
of all CPU instructions is 2 bytes (one word), so the least significant PC bit is ignored. (When an
instruction is fetched for read, the least significant PC bit is regarded as 0.)
2.4.3
EXR does not affect operation in this LSI.
2.4.4
This 8-bit register contains internal CPU status information, including an interrupt mask bit (I) and
half-carry (H), negative (N), zero (Z), overflow (V), and carry (C) flags. Operations can be
performed on the CCR bits by the LDC, STC, ANDC, ORC, and XORC instructions. The N, Z, V,
and C flags are used as branching conditions for conditional branch (Bcc) instructions.
