Test reset input for IEEE 1149.1 boundary scan (JTAG). If JTAG will not be used,
TRST should be tied low.
Transfer start I/O from processor bus (can also come from any bus master on the
processor bus). Signals the start of either a processor or bus master cycle.
Transfer size I/O from processor bus.
Transfer type I/O from processor bus.
Write through status input from processor bus. When tied to ground, the
MPC2605 will operate in write–through mode only (no copy–back).
Power supply: 3.3 V
Ground.
No connection: There is no connection to the chip.
