• Manufacturer Part Number: pef20550
• Description: Extended Line Card Interface Controller Elic
• Manufacturer: Infineon Technologies Corporation

Together TSN and CS provide 9 bits to determine the location of the time slot for the
HDLC channel.
One of up to 64 time slots can be programmed independently for receive and transmit
direction via the registers TSAR and TSAX.
According to the value programmed via those bits, the receive/transmit window (time
slot) starts with a delay of 1 (minimum delay) up to 512 clock periods following the frame
synchronization signal and is active during the number of clock periods programmed via
RCCR, XCCR (number of bits to be received/transmitted within a time slot) as shown in
figure 42.
