2 Daughterboard Support
A 24-ball TBGA (TBGA-24B) package for Xccela Flash is supported on a dedicated daughterboard,
which can be connected to the ZedBoard for testing.

TBGA-24B (6mm x 8mm, 5x5 ball grid array) is supported on FMC_0007_SNOR_TBGA_V2.0, while
signal test port is also reserved on the daughterboard.

SW1 and SW2 are used for pull-up/pull-down for HOLD# and WP#. These two switches must be
configured as follows:
FMC_0007_SNOR_TBGA V2.0 Setting
SW Description Setting
SW1 HOLD# pull up/down SW1-1 on, SW1-2 off (pull-up on, pull-down off)
SW2 WP# pull up/down SW1-1 off, SW1-2 on (pull-up on, pull-down off)
IMPORTANT:
The two sub-switches on SW1 and SW2 cannot be enabled at the same time;
this would cause the power to be short to ground.
