Table 2-1. Signal Index (Continued)
Provides thermal sensing information.
Power supply.
Indicates the need to rerun the bus cycle.
Indicates an error condition exists for a bus transfer.
Indicates the slave cannot handle a line burst access.
Indicates the current bus transfer should not be cached.
Indicates the MC68060 should snoop bus activity while it is not the bus master.
Asserted by the processor to request bus mastership.
Asserted by an arbiter to grant bus mastership privileges to the processor.
Qualifies BG by indicating the degree of necessity for relinquishing bus owner-
ship when BG is negated.
Indicates the MC68060 has relinquished the bus in response to the external ar-
biter’s negation of BG.
Asserted by the current bus master to indicate it has assumed ownership of the
bus.
Dynamically disables the internal caches to assist emulator support.
Disables the translation mechanism of the MMUs.
Processor reset.
Asserted during execution of a RESET instruction to reset external devices.
Provides an encoded interrupt level to the processor.
Indicates an interrupt is pending.
Used during an interrupt acknowledge transfer to request internal generation of
the vector number.
Clock input used for all internal logic timing.
Defines the speed of the system bus clock to be full, 1/2, or 1/4 the speed of the
processor clock.
Selects between IEEE 1149.1 compliance operation and emulation mode oper-
ation.
Clock signal for the IEEE P1149.1 test access port (TAP).
Selects the principal operations of the test-support circuitry.
Serial data input for the TAP.
Serial data output for the TAP.
Provides an asynchronous reset of the TAP controller.
Ground connection.
