X and Y are 16-bit general purpose registers.
A is a 24-bit Accumulator. The output of the ALU is sent to this register. When 16-bit data
is transferred into this register, it goes into the 16 MSBs and the least significant eight bits
are set to zero. Only the upper 16 bits are transferred to the destination register when the
Accumulator is selected as a source register in transfer instruction.
SR is the Status Register that contains the ALU status and the control bits listed in
Table 3. The status register is always read in its entirety. S15-S12 are set/reset by the
hardware and can only be read through software. They are set or reset by the ALU after an
operation.
S8-S0 can be written by software. S8, if 0 (reset), allows the hardware to overflow. If S8 is
set, the hardware clamps at maximum positive or negative values instead of overflowing.
S7 enables interrupts. S6–S5 are used for “short form direct” addresses, which are
described below. The definitions of S2-S0 are listed in Table 4.
