4.1.3.2 OE Pins and Slew Rate Control

Low and high voltage level can be set on all the pins using GUI without the need of onboard headers. By default, the LMKDB1104EVM is set to control OE pins through the header jumpers. To control the OE pins using software, remove jumper header J14, SBI_PRIMARY. After removing jumper header J14, OE pins cannot be controlled through the OE pin jumper headers.

Table 4-3 OE# Pins
Pin Level Function
Low (default) LMKDB1104 has CLK# active. To control OE pin through the MSP430, make sure to remove jumper header J14
High LMKDB1104 has CLK# inactive. To control OE pin through the MSP430, make sure to remove jumper header J14.
Table 4-4 SLEWRATE_PIN
Pin Level Function
Low (default) All outputs are set to a slow slew rate.
High All outputs are set to a high slew rate.
Hi-Z When Hi-Z is selected, on-board header jumper JP1 can be used to force external voltages on the pin.
