3.3.2 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 may also be
used as a temporary storage area.
3.3.3 Condition Code Register (CCR)
The CCR is a 5-bit register in which the H, N, Z, and C bits are used to
indicate the results of the instruction just executed, and the I bit is used
to enable interrupts. These bits can be individually tested by a program,
and specific actions can be taken as a result of their state. Each bit is
explained in the following paragraphs.
3.3.3.1 Half Carry (H)
This bit is set during ADD and ADC operations to indicate that a carry
occurred between bits 3 and 4.
3.3.3.2 Interrupt (I)
When this bit is set, the timer and external interrupt is masked (disabled).
If an interrupt occurs while this bit is set, the interrupt is latched and
processed as soon as the I bit is cleared.
3.3.3.3 Negative (N)
When set, this bit indicates that the result of the last arithmetic, logical,
or data manipulation was negative.
