4.1.2.2 EVM Setup

EVM setup has key pins to configure device. Table 4-1 and Table 4-2 outline usage of each pin option.

Table 4-1 CLKPWRGD_PD#
Pin Level Function
Low LMKDB1112 power down mode.
High LMKDB1112 normal operation mode (default).
Hi-Z When Hi-Z is selected, on-board header jumper CKPWRGD_PD# can be used to force external voltages on the pin.
Table 4-2 SBEN_MUX
Pin Level Function
Low SBEN MUX (U6) configured to OE option for pin OE4#, OE7# and OE10# through IO expander (default).
High SBEN MUX (U6) 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.
