Register 0x1024: RUL3 POS Level 3 Configuration
PAUSE[1:0]:
The PAUSE[1:0] bits specifies the minimum number of clock cycles the POS-PHY Level 3
interface will pause between transfer bursts. When PAUSE[1:0] is set to “00”, the POS-
PHY Level 3 interface may select the next channel by immediately asserting RSX after
ending a transferred. When PAUSE[1:0] is set to “11”, the POS-PHY Level 3 interface will
wait for 3 RFCLK clock cycles before selecting the next channel and starting another
transfer.
The PAUSE[1:0] register allows the user to configure the POS-PHY Level 3 interface to
halt between burst transfers. By inserting dead-time between bursts, the Layer device may
cleanly pause the transfer of data between bursts by deasserting RENB.
