Name
Function
0
DE_CLK1UP Setting this bit to a logic high enables the transmit
function for CLK1 Update.
1
DE_CLK3UP Setting this bit to a logic high enables the transmit
function for CLK3 Update.
[3..2] -
no function
write as 0 and ignore when read
4
nRE_CLK1 Clearing this bit enables global the read function for
CLK1
Note: A signal can only be received or transmitted over CLK1, not
both. That means if the
nRE_CLK1
bit is cleared it has to be
ensured by software that all
DE_CLK1
bits and the
are cleared.
5
nRE_CLK2 Clearing this bit enables global the read function for
CLK2
Note: A signal can only be received or transmitted over CLK1, not
both. That means if the
nRE_CLK1
bit is cleared it has to be
ensured by software that all
DE_CLK1
bits and the
are cleared.

nRE_UP
Clearing this bit enables the read function for CLK1
update and CLK3 update
7 -
no function
write as 0 and ignore when read
