TAB1 (Transfer data to Accumulator and register B from timer 1)

001010111

057

–

Grouping:

Timer operation

Description: Transfers the contents of timer 1 to regis-

ters A and B.

Operation:

(B)

← (T17–T14)

(A)

← (T13–T10)

TABE (Transfer data to Accumulator and register B from register E)

000101010

02A

–

Grouping:

Description: Transfers the contents of register E to reg-

isters A and B.

← (ER3–ER0)

TABP p (Transfer data to Accumulator and register B from Program memory in page p)

01001p3

09p

–

0/1

–

Grouping:

Arithmetic operation

Description:

Transfers bits 7 to 4 to register B and bits 3 to 0 to register

A when URS flag is cleared to “0.” These bits 7 to 0 are the

ROM pattern in address (DR2 DR1 DR0 A3 A2 A1 A0) speci-

fied by registers A and D in page p.

Transfers bit 8 of ROM pattern is transferred to flag CY when

URS flag is set to “1” (after the URSC instruction is executed).

(One of stack is used when the TABP p instruction is executed.)

Operation:

SK(SP))

← (PC) , (SP) ← (SP) + 1

(PCH)

← p, p = 0 to 7, (PCL) ← (DR2–DR0, A3–A0)

When URS = 0,

(B)

← (ROM(PC))7 to 4, (A) ← (ROM(PC))3 to 0

When URS = 1,

(CY)

← (ROM(PC))8

(B)

← (ROM(PC))7 to 4, (A) ← (ROM(PC))3 to 0

(SP)

← (SP) – 1, (PC) ← (SK(SP))

Note:

p is 0 to 7 for M34282M1,

p is 0 to 15 for M34282M2/E2.

Description: Transfers the contents of timer 2 to regis-

ters A and B.

Operation:

(B)
