0: Ignore the EOS character during reading.
1: The reading is stopped while the EOS character is read.
ibcEOSwrt
0x000D
0: The
EOI line
is not set to enable while the
EOS
character is sent during
writing.
1: The
EOI line
is set to enable while the
EOS
character is sent during
writing.
ibcEOScmp
0x000E
0: Compare all
EOS
with 7 bits.
1: Compare all
EOS
with 8 bits.
ibcEOSchar
0x000F
