Serial Interface with Time Slot Assigner
7.8.4.5 PROGRAMMING SI RAM ENTRIES. The programming of each word within the
RAM determines the routing of the serial bits (or bit groups) and the assertion of strobe out-
puts. The RAM programming codes are as follows:
Bit 15 LOOP (Loop back this time slot)
SWTR—Switch Tx and Rx
7-72
LOOP
15
The SWTR bit is only valid in the receive route RAM and is ignored in the transmit route
RAM. This bit affects the operation of both the L1RXD and L1TXD pins
The SWTR bit would only be set in a special situation where the user desires to receive
data from a transmit pin and transmit data on a receive pin. For instance, consider the sit-
uation where devices A and B are connected to the same TDM, each with different time
slots. Normally, there is no opportunity for stations A and B to communicate with each oth-
er directly over the TDM, since they both receive the same TDM receive data and transmit
on the same TDM transmit signal (see Figure 7-27).
NOTES:
1: Only available on REV C mask or later. NOT Available on REV A or B.
Rev A mask is C63T
Rev B mask are C69T, and F35G
Current Rev C mask are E63C, E68C and F15W
