Grouping: Timer operation
Description: Transfers the high-order 4 bits (T47–T44) of
timer 4 to register B.
Transfers the low-order 4 bits (T43–T40) of

Operation:
In A/D conversion mode (Q13 = 0),
(B) ← (AD9–AD6)
(A) ← (AD5–AD2)
In comparator mode (Q13 = 1),
(B) ← (AD7–AD4)
(A) ← (AD3–AD0)
(Q13 : bit 3 of A/D control register Q1)
Grouping:
Description:
A/D conversion operation
In the A/D conversion mode (Q13 = 0), trans-
fers the high-order 4 bits (AD9–AD6) of
register AD to register B, and the middle-or-
der 4 bits (AD5–AD2) of register AD to
register A. In the comparator mode (Q13 = 1),
transfers the middle-order 4 bits (AD7–AD4)
of register AD to register B, and the low-order
4 bits (AD3–AD0) of register AD to register A.

Grouping: Register to register transfer
Description: Transfers the high-order 4 bits (E7–E4) of
register E to register B, and low-order 4 bits
of register E to register A.

Operation:
(SP) ← (SP) + 1
(SK(SP)) ← (PC)
(PCH) ← p
(PCL) ← (DR2–DR0, A3–A0)
(DR2) ← 0
(DR1, DR0) ← (ROM(PC))9, 8
(B) ← (ROM(PC))7–4
(A) ← (ROM(PC))3–0
(PC) ← (SK(SP))
(SP) ← (SP) – 1
Grouping: Arithmetic operation
Description: Transfers bits 9 and 8 to register D, bits 7 to 4
to register B and bits 3 to 0 to register A.
These bits 7 to 0 are the ROM pattern in ad-
dress (DR2 DR1 DR0 A3 A2 A1 A0)2 specified
by registers A and D in page p.
Note: p is 0 to 15 for M34518M2, and p is 0 to 31 for
M34518M6, p is 0 to 47 for M34518M6, and p is 0 to
63 for M34518M8E8.
When this instruction is executed, be careful not to over
the stack because 1 stage of stack register is used.
