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).
