4.3.2. GIRTXGENCR - Transmit Clock Generator Control Register [16] (+0x04)

This register holds the value of the divisor to be applied to the internal programmable divider for the Transmit functions.

Table 4.3. GIRTXGENCR bit functions

Bit	Name	Function
15:0	ckdiv	Divisor value for the programmable divider/clock generator. Value of 0 is reserved. Value of 1 will result in divide by 2. Value of 2 will result in divide by 3, and so on.

Bit

Name

Function

15:0

ckdiv

Divisor value for the programmable divider/clock generator.

Value of 0 is reserved.

Value of 1 will result in divide by 2.

Value of 2 will result in divide by 3, and so on.

When the TX function is disabled, the value written to this register is applied directly to the internal programmable TX clock divider. When the TX function is enabled, changes to this register value only take effect when the associated internal counter reaches zero.
