d7 (MP):

Indication of pause at time of marker code detection

(0: Indication of continuation/restart, 1: Indication of temporary pause)

If this MP bit is in advance set to 1 in decoding, the decoding temporarily pauses at the time of marker

code detected.

(When the ME bit is set to 1, an interruption occurs when marker code is detected.)

When decoding process is not completed at time of temporary pause of marker detection, the register for

setting the number of lines can be respecified (see item (7)). Afterwards, setting this MP bit to 0 restarts

the decoding process (the decoding process is carried out for the number of set lines).

(6) Register for setting the number of pixels (W/R)

d0 to 7 (PEL_L):

Sets the number of pixels in a line. (Low byte)

d0 to 5 (PEL_H):

Sets the number of pixels in a line. (Upper byte)

A maximum of 8192 pixels can be set at the 3-line template. A maximum of 10240 pixels

can be set at the 2-line template.

Set the number of pixels to be actually coded (decoded) at time of scale-up (scale-down).

When the image data bus is 16 bits (32 bits) with the parallel I/F selected, set the number of

pixels to multiples of 16 (multiples of 32).

With the serial I/F selected, set the number of pixels to multiples of 8.

d0 to 7 (LSET_L):

Sets the number of lines to be processed. (Low order byte) (1 to 65535: 0 line is not allowed.)

d0 to 7 (LSET_H):

Sets the number of lines to be processed. (High order byte)

At time of scale-down (scale-up), set the number of lines to be actually coded (decoded).

Set the number of lines (number of relative lines) ranging from the processing start command

to be issued next to the temporary stop/termination end just after. This register must be set to

a specific value before the issuance of the process start command.

As far as the following conditions are satisfied, this register can be rewritten in the course of

processing.

• When the maximum value (65535) is set before issuance of the processing start command,

an arbitrary value can be set once in the course of processing.

• When a value except for the maximum value (65535) is set before issuance of the

processing start command, and the value requires to be respecified in the course, respecify

the maximum value (65535) once and then respecify a desired value.
