  Set the state of the device RST pin.
 
 Parameters:
- state: The device RST pin is set to state (0/1).
+ state: The device RST pin is set to state (0, 1, 2, 3).
 
 Returns:
 
 Notes:
+ 1. As implemented, a state == 0 asserts RST (active low), while a state == 1 tri-states RST.
+    Thus, a pull-up resistor on RST is assumed.
+ 2. As implemented, EN_TCLK and RST are negative logic.
