Channel Mode
This is a per channel setting with the following options set as the register value as below, If a system
is set such that a PWM/Counter mixed mode is detected the system will not allow counter mode to
be initialised.

Input Health
If a PWM channel times out during pulse measurement 3 times in a row the system will mark the
channel as dead and skip it on subsequent channel reads. A system reset (either invoked via
Modbus configuration register) or a power cycle will clear these registers.
This prevents total Modbus lock out in the situation that multiple sensors lose power or are non-
responsive.
