E05A03

Functions

Lower Address

R/W

Name

Function

INO

IN7

Reads the data which was latched using STROBE, and resets

OOH

the STROBE-BUSY output.

Writes data to the upper eight bits of the 24-bit

shift register

—

(DB7

DBO

Bits 23 -

16).

STRB

Bit 7: 1 (Indicates the trailing edge of the STROBE signal.)

HOME

Bit 6: 1 (The HOME input is HIGH.)

OIH

Writes data to the middle eight bits of the 24-bit shift register

—

(DB7

DBO

Bits 15

- 8).

INO

- IN7 Directly reads

INO

IN7. Does not affect the BUSY signal.

02H

Writes data to the lower eight bits of the 24-bit shift register

—

(DB7

DBO

Bits 7 - o).

Reads the MSB of the 24-bit shift register and shifts the data

—

one bit to the left

(MSB

DB7).

Bit 7: 1 (The BUSY signal is output at the leading edge of

STROBE.)

O (The BUSY signal is output at the trailing edge of

BUSY

STROBE.)

Bit 6: 1 (Resets software-BUSY.)

03H O (Sets software-BUSY.)

NLQLP

Bit 4: 1

(NLQLP

is LOW.) ● See NOTES 2.

(NLQLP

is HIGH.)

CNDLP

Bit 3: 1

(CNDL

is LOW.) ‘See NOTES 2.

(CNDL

is HIGH.)

Bit 2: 1

(PE

is HIGH and

PELP

LOW.)

PELP

(PE

is LOW and

PELP

HIGH.)

Latches (and inverts) the data for pins 1 - 8 of the

printhead.

04H

HD1

- HD8

(DB7

DBO

HD1

- HD8 Data is output when FIRE goes

LOW.)

05H

HD9

Latches (and inverts) the data for pin 9 of the

printhead.

(DB7

HD9 Data is output when FIRE goes LOW.)

06H

w PFA - PFD

Latches the phase data for the PF motor.

(DB7

DB4

PFA - PFD)

07H

——

CRA - CRD

Latches the phase data for the CR motor.

(DB3

DBO

CRA

- CRD)

NOTES: 1. The above functions are mapped to every eight bytes from COOOH to DFFFH.

2. These are not used in this printer.
