System Monitor Status/Control Register (Read/Write) – (BAR0 + 0x300300)
This read/write register will access the system monitor register at the
address set in the System Monitor Address Register.
For example, the address of the System Monitor Status register that is to be
accessed is first set via the System Monitor Address register at BAR0 plus
0x300304. Next, this register at BAR0 plus 0x300300 is read. Bits 22 to 16
of this register hold the address of the system monitor register that is
accessed. Data bits 15 to 6 of this register hold the “ADCcode” temperature,
Vccint, or Vccaux value. Data bits 5 to 0 are not used. Valid addresses are
given in column one of the table below.
Reading or writing this register is possible via 32-bit data transfers.
The 10-bits digitized and output from the ADC can be converted to
temperature by using the following equation.

System Monitor Address Register (Write Only) – (BAR0 + 0x300304)
This write only register is used to set the system monitor address register
with a valid address for the System Monitor internal status or control
registers. Valid addresses are given in the following table. Additional
addresses can be found in the Xilinx System Monitor document UG370
(available from Xilinx). Writing this register is possible via 32-bit data
transfers.
The address value written to this register can be read on bits 22 to 16 of the
System Monitor Status/Control register at BAR0 plus 0x300300.
