Table 3.18 GPIO and LED signals
Signal Name BGA Position Type Strength Description
GPIO[7:0] K25, L23,
L25, M25,
H25, K24,
AE25, AC23 I/O 8 mA General purpose I/O pins. The LSI53C1030
controls these signals and can configure them
as inputs or as outputs. These pins default to
input mode after chip initialization.
A_LED/ J23 O 12 mA A_LED/ either drives the SCSI Channel [0]
activity LED or provides a General Purpose
I/O pin. A_LED can be controlled by firmware
or driven by chip activity.
B_LED/ K23 O 12 mA B_LED/ either drives the SCSI Channel [1]
activity LED or provides a General Purpose
I/O pin. B_LED/ can be controlled by firmware
or driven by chip activity.
HB_LED/ C25 O 12 mA Firmware blinks Heart Beat LED at a
1.0 second interval when the IOP is
operational.
