1.6.1 Reset Bit

If the SMT clock prescaler is set to any value other than '00', setting the RST bit will cause the module to stop working. The RST bit will remain at the value '1', the counter will not increment, and no interrupts will be generated. The problem is cleared by turning the module off and on or by performing a device reset.

Work around

Method 1:

Do not set the RST bit; manual reset is usually not required for typical operation because the measurement logic will reset the counter automatically.

Method 2:

Write zero to the counter manually. Either disable the module or the clock before using this method.

Method 3:

Use 1:1 prescaler (PS = 00).

Method 4:

Use the CLKREF subsystem to provide a prescaled clock and set PS = 00.
