ST.A
Store Word from Address Register
Description
Store the value in address register A[a] to the memory location specified by the addressing mode.
Note:If the source register is modified by the addressing mode, the value stored to memory is undefinded.
ST.Aoff18, A[a] (ABS)(Absolute Addressing Mode)
EA = {off18[17:14], 14b'0, off18[13:0]};
M(EA, word) = A[a];
ST.AA[b], off10, A[a] (BO)(Base + Short Offset Addressing Mode)
EA = A[b] + sign_ext(off10);
M(EA, word) = A[a];
ST.AP[b], A[a] (BO)(Bit-reverse Addressing Mode)
index = zero_ext(A[b+1][15:0]);
incr = zero_ext(A[b+1][31:16]);
EA = A[b] + index;
M(EA, word) = A[a];
new_index = reverse16(reverse16(index) + reverse16(incr));
A[b+1] = {incr[15:0], new_index[15:0]};
ST.AP[b], off10, A[a] (BO)(Circular Addressing Mode)
index = zero_ext(A[b+1][15:0]);
length = zero_ext(A[b+1][31:16]);
EA = A[b] + index;
M(EA, word) = A[a];
new_index = index + sign_ext(off10);
Store the value in address register A[a] (instruction format BO, SSR, SSRO or SSR) or A[15] (instruction format
SRO or SC) to the memory location specified by the addressing mode.
Note:If the source register is modified by the addressing mode, the value stored to memory is undefinded.
