This terminal enables IC to operate. IC is Standby at HIGH in
this terminal. IC can operate at LOW in this terminal.
This terminal resets the whole IC including a logic. This terminal
resets IC at HIGH. This terminal cancel resetting IC at the edge
from HIGH to LOW. IC includes power on reset function. The
control from external is also possible. The reset term in IC
takes OR between power on reset and control signal from
external.
While
countermeasures circuit of integration condenser is active.

Set up current value of each bit is on the right table.
The number of input clock and set up clamp level is as follows.
Clamp level is established with fall edge of input clock.
It repeats the same value after 16 clock.
This terminal sets up clamp level.
As including D/A of 4bit,16way clamp level setting is possible by
inputting clock after reset is canceled(include none clamp).
