TSPC860 [Preliminary]
2129B–HIREL–12/04
WE0
BS_B0
IORD
High
C7
Output
Write Enable 0—Output asserted when a write access to an external
slave controlled by the GPCM is initiated by the TSPC860
.
WE0
is
asserted if D(0-7) contains valid data to be stored by the slave
device.
Byte Select 0 on UPMB—Output asserted under control of the
UPMB, as programmed by the user. In a read or write transfer, the
line is only asserted if D(0-7) contains valid data.
IO Device Read—Output asserted when the TSPC860 starts a read
access to a region controlled by the PCMCIA interface. Asserted
only for accesses to a PC card I/O space.
WE1
BS_B1
IOWR
High
A6
Output
Write Enable 1—Output asserted when the TSPC860 initiates a
write access to an external slave controlled by the GPCM. WE1 is
asserted if D(8-15) contains valid data to be stored by the slave
device.
Byte Select 1 on UPMB—Output asserted under control of the
UPMB, as programmed by the user. In a read or write transfer, the
line is only asserted if D(8-15) contains valid data.
I/O Device Write—This output is asserted when the TSPC860
initiates a write access to a region controlled by the PCMCIA
interface. IOWR is asserted only if the access is to a PC card I/O
space.
WE2
BS_B2
PCOE
High
B6
Output
Write Enable 2—Output asserted when the TSPC860 starts a write
access to an external slave controlled by the GPCM. WE2 is
asserted if D(16-23) contains valid data to be stored by the slave
device.
Byte Select 2 on UPMB—Output asserted under control of the
UPMB, as programmed by the user. In a read or write transfer,
BS_B2 is asserted only D(16-23) contains valid data.
PCMCIA Output Enable—Output asserted when the TSPC860
initiates a read access to a memory region under the control of the
PCMCIA interface.
WE3
BS_B3
PCWE
High
A5
Output
Write Enable 3—Output asserted when the TSPC860 initiates a
write access to an external slave controlled by the GPCM. WE3 is
asserted if D(24-31) contains valid data to be stored by the slave
device.
Byte Select 3 on UPMB—Output asserted under control of the
UPMB, as programmed by the user. In a read or write transfer,
BS_B3 is asserted only if D(24-31) contains valid data.
PCMCIA Write Enable—Output asserted when the TSPC860
initiates a write access to a memory region under control of the
PCMCIA interface.
BS_A(0-3)
High
D8, C8,
A7, B8
Output
Byte Select 0 to 3 on UPMA—Outputs asserted under requirement
of the UPMB, as programmed by the user. For read or writes,
asserted only if their corresponding data lanes contain valid data:
BS_A0 for D(0-7), BS_A1 for D(8-15),
BS_A2 for D(16-23), BS_A3 for D(24-31)
