R.25W39 Datasheet Counter/Timer (C/T) The counter timer is a 16 bit programmable divider that operates one of three modes: Counter, Timer or Time Out mode. In all three modes it uses the 16-bit value loaded to the CTUR and CTLR registers. (Counter timer upper and lower preset registers).

Internal metal electrodes are added at each end and connected by a resistive paste which is applied to the top surface of the substrate. The composition of the paste is adjusted to give the approximate resistance required and the value is trimmed to within tolerance, by laser cutting of this resistive layer. |
