W83601R/G  
CR15 Power LED Configuration Register (Default 0x00, Read/Write)  
Priority of LED function is highest.  
Bit 7: = 1, Enable the LED function. 0, Disable the LED function.  
When the LED function is enabled, GP function is ignored, no matter it is input or output.  
Bit 6-4: LED frequency selection.  
= 111, the LED pin is tri-state (OD pin) or driven high (O pin).  
= 110, the LED pin is a 1 Hz toggle pulse with 50 duty cycle.  
= 101, the LED pin is a 1/2 Hz toggle pulse with 50 duty cycle.  
= 100, the LED pin is a 1/4 Hz toggle pulse with 50 duty cycle.  
= 000, the LED pin is driven low.  
Bit 3: GP port selection.  
0, GP port 1 is set to the LED function if bit 7 is set to 1.  
1, GP port 2 is set to the LED function if bit 7 is set to 1.  
Bit 2-0: GP pin selection.  
=110-000, GP16-GP10 can be selected as LED output when bit 3 is 0.  
=101-011, GP25-GP23 can be selected as LED output when bit 3 is 1.  
CR16-1F Reserved Register  
CR20 (Chip ID High Byte, Read Only)  
Bit 7-0: = 0x60.  
CR21 (Chip ID Low Byte, Read Only)  
Bit 7-0: = 0x13 (for the W83601R/G).
