MACHINE INSTRUCTIONS (INDEX BY ALPHABET)
A n (Add n and accumulator)
000110nnnn
06n
11
Overflow = 0
Grouping:
Arithmetic operation
Description: Adds the value n in the immediate field to
register A, and stores a result in register A.
The contents of carry flag CY remains un-
changed.
Skips the next instruction when there is no
overflow as the result of operation.
Executes the next instruction when there is
overflow as the result of operation.
Operation:
(A)
← (A) + n
n = 0 to 15
ADST (A/D conversion STart)
1010011111
29F
11
Grouping:
A/D conversion operation
Description: Clears (0) to A/D conversion completion
flag ADF, and the A/D conversion at the A/D
conversion mode (Q13 = 0) or the compara-
tor operation at the comparator mode (Q13
= 1) is started.
Operation:
(ADF)
← 0
Q13 = 0: A/D conversion starting
Q13 = 1: Comparator operation starting
(Q13 : bit 3 of A/D control register Q1)
AM (Add accumulator and Memory)
0000001010
00A
11
Grouping:
Arithmetic operation
Description: Adds the contents of M(DP) to register A.
Stores the result in register A. The contents
of carry flag CY remains unchanged.
Operation:
(A)
← (A) + (M(DP))
AMC (Add accumulator, Memory and Carry)
0000001011
00B
11
0/1
Grouping:
Arithmetic operation
Description: Adds the contents of M(DP) and carry flag
CY to register A. Stores the result in register
A and carry flag CY.
Operation:
(A)
← (A) + (M(DP)) + (CY)
(CY)
← Carry
