4.1.2.2 EVM Setup

EVM setup has key pins to configure device. The tables below outlines usage of each pin option.

Table 4-1 CLKPWRGD_PD#
Pin Level Function
Low LMKDB1120 power down mode.
High LMKDB1120 normal operation mode (default).
Hi-Z When Hi-Z is selected, on-board header jumper JP24 can be used to force external voltages on the pin.
Table 4-2 SBEN_MUX
Pin Level Function
Low SBEN MUX (U4) configured to OE option for pin OE5#, OE6# and OE10# through IO expander (default).
High SBEN MUX (U4) switches to USB2ANY MCU for SBI_IN, SBI_DATA, and SHFT_LD#. SBI becomes available after power reset in this setting on the device. Output page have Enable SBI Control button to configure all the setting automatically.
Hi-Z When Hi-Z is selected, on-board header jumper can be used to force external voltages on the pin.
