2.6 Onboard Isolated Counter/Timer
The UNO-2050G uses one 82C54 programmable timer/counter chip that
includes three independent 16-bit down counters: counter 0, counter 1
and counter 2. Counter 0 and counter 1 are for users, and counter 2 is
specified for the system and can’t be used by user. Each counter has clock
input, gate input and pulse output. They can be programmed to count
from 2 up to 65535 or cascaded into one 32-bit counter.
The UNO-2050G has 2 isolated counter input channels designated DI6
and DI7 or 2 isolated timer output channels designated DO6 and DO7.
Therefore, you can set each counter of 82C54 as counter function or timer
function.
