Data Sheet
Signal Name
Main system clock input.
Set to 1 when a machine check is generated.
Processor timer external input clock.
Main system reset. External logic can drive this bidirectional pin
low (minimum of 16 cycles) to initiate a system reset. A system
reset can also be initiated by software. Implemented as an open-
drain output (two states; 0 or open circuit).
Halt from external debugger.
General purpose I/O. To access these functions, software must
set DCR register bits.

Test Enable.
Note: Do not connect for normal operation.
Receiver Inhibit. Active only when TestEn is active. Used for
manufacturing test only.
Mode Control. Active only when TestEn is active. Used for
manufacturing test only.
Leakage Test. Active only when TestEn is active. Used for
manufacturing test only.
Reference Enable. Active only when TestEn is active. Used for
manufacturing test only.
Driver Inhibit. Active only when TestEn is active. Used for
manufacturing test only.
On-chip PNP thermal monitor transistor.
A is the emitter and B is the base. The collector is grounded.
Module characterization and screening. Use for test purposes
only. Tie down as specified in Note 3 for normal operation.
