The CMS Subsystem uses a single active-Low reset pin, aresetn_ctrl. This reset should be synchronous to aclk_ctrl and will reset the entire CMS design.

Additionally a host accessible register, MB_RESETN_REG can be used to reset the CMS MicroBlazeâ„¢ subsystem.

Note: Following power-up or assertion of aresetn_ctrl, MB_RESETN_REG will be reset to 0x0 placing the MicroBlaze subsystem into the reset state. Driver firmware will be required to write 0x1 to this register to take the MicroBlaze Subsystem out of reset and start CMS Firmware.
Note: Once CMS firmware has started, wait until the REG_MAP ready bit is set in the HOST_STATUS2_REG register before using the mailbox or reading sensor information from the REG_MAP.
