MSC8122 Technical Data, Rev. 13
1-10
Freescale Semiconductor
Signals/Connections
TT1
Input/ Output
Bus Transfer Type 1
The bus master drives this pins during the address tenure to specify the type of the transaction. Some
applications use only the TT1 signal, for example, from MSC8122 to MSC8122 or MSC8122 to MSC8101
and
vice
versa
. In these applications, TT1 functions as read/write signal.
TT[2–4]
CS[5–7]
Input/ Output
Output
Bus Transfer Type 2–4
The bus master drives these pins during the address tenure to specify the type of the transaction.
Chip Select 5–7
Enables specific memory devices or peripherals connected to the system bus.
CS[0–4]
Output
Chip Select 0–4
Enables specific memory devices or peripherals connected to the system bus.
TSZ[0–3]
Input/ Output
Transfer Size 0–3
The bus master drives these pins with a value indicating the number of bytes transferred in the current
transaction.
TBST
Input/ Output
Bus Transfer Burst
The bus master asserts this pin to indicate that the current transaction is a burst transaction (transfers
eight words).
Interrupt Request 1
1
One of fifteen external lines that can request a service routine, via the internal interrupt controller, from the
SC140 core.
IRQ1
GBL
Input
Output
Global
1
When a master within the MSC8122 initiates a bus transaction, it drives this pin. Assertion of this pin
indicates that the transfer is global and should be snooped by caches in the system.
Interrupt Request 3
1
One of fifteen external lines that can request a service routine, via the internal interrupt controller, from the
SC140 core.
IRQ3
BADDR31
Input
Output
Burst Address 31
1
Five burst address output pins are outputs of the memory controller. These pins connect directly to
burstable memory devices without internal address incrementors controlled by the MSC8122 memory
controller.
Interrupt Request 2
1
One of fifteen external lines that can request a service routine, via the internal interrupt controller, from the
SC140 core.
IRQ2
BADDR30
Input
Output
Burst Address 30
1
Five burst address output pins are outputs of the memory controller. These pins connect directly to
burstable memory devices without internal address incrementors controlled by the MSC8122 memory
controller.
Interrupt Request 5
1
One of fifteen external lines that can request a service routine, via the internal interrupt controller, from the
SC140 core.
IRQ5
BADDR29
Input
Output
Bus Burst Address 29
1
Five burst address output pins are outputs of the memory controller. These pins connect directly to
burstable memory devices without internal address incrementors controlled by the MSC8122 memory
controller.
BADDR28
Output
Burst Address 28
Five burst address output pins are outputs of the memory controller. These pins connect directly to
burstable memory devices without internal address incrementors controlled by the MSC8122 memory
controller.
BADDR27
Output
Burst Address 27
Five burst address output pins are outputs of the memory controller. These pins connect directly to
burstable memory devices without internal address incrementors controlled by the MSC8122 memory
controller.
