+  Counter clock and gate source configuration.
+
+  Four config commands to set/get the gate/clock source for a counter channel:
+
+  0 ID: INSN_CONFIG_SET_GATE_SRC
+  1 gate source
+
+  0 ID: INSN_CONFIG_GET_GATE_SRC
+  1 <-- Current gate source returned here.

+  0 ID: INSN_CONFIG_SET_CLOCK_SRC
+  1 clock source
+
+  0 ID: INSN_CONFIG_GET_CLOCK_SRC
+  1 <-- Current clock source returned here.
+
+  Notes:
+  1. Gate and clock sources are hardware-specific.
+  2. 'chanspec' indicates the channel to configure (if the hardware supports
+     per-channel configuration of the gate and clock sources).
