53 Appendix C
Table C-8 Register for Digital Output
DI15 ~ DI0 Digital input data
DI0 the least significant bit (LSB) of the DI data
DI15 the most significant bit (MSB)
C.9 D/A Output — BASE+04/05H
Write-only registers BASE+04H and BASE+05H accept data for D/A
output.
The PCL-818HD/HG/L provides one D/A output channel with two dou-
ble-buffered 12-bit multiplying D/A converters. Write registers at
addresses BASE+04H and BASE+05H hold output data. DA0 is the least
significant bit (LSB) and DA11 is the most significant bit (MSB) of the
D/A data.
Table C-9 Register for D/A Output
DA11 ~ DA0 Analog to digital data
DA0 the least significant bit (LSB) of the D/A data
DA11 the most significant bit (MSB)
