ISA upper address bus lines
ISA lower address bus lines
ISA data bus lines
RESET input
Memory Read—used to enable the output drivers of the Am79C930 device for
ISA bus memory read accesses
Memory Write—used to indicate that the current ISA bus cycle is a memory
write access
Address Enable—used to indicate that the current ISA bus I/O address is valid
Bus Address Latch Enable—used to indicate that the ISA address lines are
valid
I/O Channel Ready—used to delay the termination of the current ISA bus cycle
I/O Read—this signal is asserted by the ISA host system whenever an I/O read
operation occurs
I/O Write—this signal is asserted by the ISA host system whenever an I/O write
operation occurs
IRQ4, 5, 9, 10, 11, 12servicing from the software
RFRSH
Refresh—indicates that the current ISA bus cycle is a refresh operation
PCMCIA
PCMCIA mode—selects PCMCIA or ISA Plug and Play mode
PWRDWN
Powerdown—indicates that device is in the power down mode
Memory Address Bus—these lines are used to address locations in the Flash
device, the SRAM device, and an extra peripheral device that are contained
within an Am79C930-based design
Memory Data Bus—these lines are used to write and read data to/from Flash,
SRAM, and/or an extra peripheral device within an Am79C930-based design
Flash Chip Enable—this signal becomes asserted when the Flash device has
been addressed by either the 80188 core of the Am79C930 device or by the
software through the PCMCIA interface
SRAM Chip Enable—this signal becomes asserted when the SRAM device
has been addressed by either the 80188 core of the Am79C930 device or by
the software through the PCMCIA interface
eXtra Chip Enable—this signal becomes asserted when the extra peripheral
device has been addressed by the 80188 core of the Am79C930 device (XCE
is not accessible through the system interface)
Memory Output Enable—this signal becomes asserted during reads of devices
located on the memory interface bus
Memory Write Enable—this signal becomes asserted during writes to devices
located on the memory interface bus
TCK
Test Clock—this is the clock signal for IEEE 1149.1 testing
TDI
Test Data In—this is the data input signal for IEEE 1149.1 testing
TDO
Test Data Out—this is the data output signal for IEEE 1149.1 testing
TMS
Test Mode Select—this is the test mode select for IEEE 1149.1 testing
TRST
Test Reset—this is the reset signal for IEEE 1149.1 testing
Test pin—when asserted, this pin places the Am79C930 device into a
non-IEEE 1149.1 test mode
Clock input to drive BIU, 80188 core, and TAI, supplying network data rate
information
