4.20 Battery Holder ﴾J2101﴿
A 3 V lithium battery ﴾CR1220﴿ can be installed for buffering the real‐time clock on the connected Mer‐
cury FPGA/SoC module. The battery is not included. Used batteries should be disposed of according to
the manufacturer's instructions.
Alternatively, the VCC_BAT_IN power signal can be driven via pin 6 of connector J2001. Refer to Sec‐
tion 4.22 for details.
Table 21 shows the characteristics of the battery holder used on the Mercury+ PE3 base board.

4.21 JTAG Connector ﴾J2003﴿
The JTAG routing depends on the presence of a FMC Mezzanine card. If a FMC card is mounted on the
Mercury+ PE3 base board, the JTAG is routed through the mounted FPGA/SoC module and the FMC card.
Otherwise, the JTAG loop includes only the FPGA/SoC module.
Figure 11 describes the routing of the JTAG signals.
