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 unchanged.
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 regis-
ter A and carry flag CY.
Operation:
(A)
← (A) + (M(DP)) + (CY)
(CY)
← Carry
