FUNCTIONAL DESCRIPTION
17
The base address for the T1devices is 60,000,000H.
The devices that need a CS are:
PM4388 TOCTL use !A20 & !A19 & !A18 & !BRDCS1 (CS6), T1_1 - T1_8 FRAMER
PM4314 QDSX use !A20 & !A19 & A18 & !BRDCS1 (CS6), T1_1 - T1_4 LIU
PM4314 QDSX use !A20 & A19 & !A18 & !BRDCS1 (CS6), T1_5 - T1_8 LIU
The base address for the DS3 devices is 70,000,000H.
TXC-03401 DS3F use !A20 & A19 & A18 & !BRDCS2 (CS7), DS3_1
TXC-03401 DS3F use A20 & !A19 & !A18 & !BRDCS2 (CS7), DS3_2
NOTE: Fast Ethernet modules on this board do not use any signal from the logic controls except for RESET
signal to the FE transceiver.
3•9 8260ADS to 8260TCOM Connectors
The physical connection from the MPC8260ADS to the MPC860TCOM board is done by the two 128 pin
connectors. One connector contains 16 Address lines, 16 Data lines, CS6 and CS7 signals, WE0, WE1,
ALE, BCTL0, GPL0 - GPL5, RESET, IRQ and CLOCK. Other signals are for showing the connected board
status and rev. The status shown is one of 4 DS3 loopback option, DS3_1 and DS3_2 enable. The other
