\brief Initialization routine for High Speed Clock

---

CONFIGURE_CHANNEL_MODE_0:

Initialize High Speed Clock Output

BYTE 0	BYTE 1	BYTE 2	BYTE 3	BYTE 4	BYTE 5	BYTE 6	BYTE 7
0xC0	Pin To Set (TO HS Clock)	0x1D (HS Clock )	Frequency LSB	Frequency MidLB	Frequency MidHB	Frequency MSB	0x55

Frequency : Desired output frequency

Response:

Command is returned with frequency set to the hardware (due to integer round off error). Actual output may vary up to an additional 2% due to internal oscillator variation.

Examples:

Set pin 19 to HS Clock, 1 MHz (0x000F4240)

0xC0 0x13 0x1D 0x40 0x42 0x0F 0x00 0x55

---

CONFIGURE_CHANNEL_MODE_19:

Disable High Speed Clock Output. Turns off Clock generation output, and makes the pin Digital out low.

BYTE 0	BYTE 1	BYTE 2	BYTE 3	BYTE 4	BYTE 5	BYTE 6	BYTE 7
0xC0	Pin To Set (TO HS Clock)	0x1D (HS Clock )	0x55	0x55	0x55	0x55	0x55

Response:

Echoed back

Examples:

Disable pin 19 HS Clock

0xDB 0x13 0x1D 0x55 0x55 0x55 0x55 0x55
