3.4 Index Register (X)
The index register is an 8-bit register used for the indexed addressing
value to create an effective address. The index register also may be
used as a temporary storage area.
3.5 Condition Code Register (CCR)
The CCR is a 5-bit register in which four bits are used to indicate the
results of the instruction just executed, and the fifth bit indicates whether
interrupts are masked. These bits can be tested individually by a
program, and specific actions can be taken as a result of their state.
Each bit is explained in the following paragraphs.
3.5.1 H — Half Carry
This bit is set during ADD and ADC operations to indicate that a carry
occurred between bits 3 and 4.
3.5.2 I — Interrupt
When this bit is set, timer and external interrupts are masked (disabled).
If an interrupt occurs while this bit is set, the interrupt is latched and
processed as soon as the interrupt bit is cleared.
3.5.3 N — Negative
When set, this bit indicates that the result of the last arithmetic, logical,
or data manipulation was negative.
