Selects expansion in lengthwise direction during decoding. (0: Equal dimension, 1: 2 expansion)
Selects expansion sideways during decoding. (0: Equal dimension, 1: 2 expansion)
d0 and d1 are possible only during decoding.
Selects reduction in lengthwise direction during coding. (0: Equal dimension, 1: 1/2 reduction)
Selects sideways reduction during coding. (0: Equal dimension, 1: 1/2 reduction)
d2 and d3 are possible only during coding.
Selects thinning in sideways direction during coding. (0: Simple thinning, 1: OR processing)
This reduction is valid only during coding.
Notes: 1. This lengthwise 1/2 reduction during coding is used for the simple thinning. (Odd lines are
This selects if the leading 1 byte is discarded during decoding. (0: Normal processing (No discarding), 1:
The leading 1 byte is discarded)
If a command to start processing the first the stripe decoding is issued during decoding while OB is set to
"1", the leading 1 byte of the input data is discarded. (Not used for decoding) If OB = 0, the one of byte
discarding process is not used. (Normal decoding used) For example, this function is used by the Host 16
bits bus when the leading 1 byte of the input data word is an invalid data.
Note: Selecting this function is valid in case of the host 8 bits bus and the external context mode also.
The end marker code used during coding is set. (SDNORM = 02h, SDRST = 03h)
The byte set to this register is outputted as the end marker during coding.
The marker codes detected during decoding are read out.
(SDNORM = 02h, SDRST = 03h, ABORT = 04h, etc.)
The marker codes detected during decoding read out as is.
