Native Function and TERM Bit Setting
Certain native function signals that are muxed onto GPIO pins support dynamic termination override, which allows the native controller to dynamically control the integrated pull-up / pull-down resistors on the signals. For those native function signals, when used, software must program the TERM bit field in the corresponding GPIO’s Pad Configuration DW1 to 1111b. The table below shows the native function signals that support dynamic termination override:
| Native Function | Signal With Dynamic Termination Override |
|---|---|
| Intel®HD Audio | HDA_SDI[0:1], HDA_SDO, HDA_SYNC, I2S[5:0]_SCLK, I2S[2:0]_SFRM, I2S[2:0]_RXD, DMIC_DATA[1:0], SNDW[3:0]_DATA |
| Power Management | ACPRESENT, WAKE#, SOC_WAKE# |
| Touch Host Controller (THC) | THC0_SPI1_IO[3:0], THC0_SPI2_IO[3:0] THC1_SPI2_IO[3:0] |
| Thunderbolt / BSSB | TBT_LSX[3:0], BSSB_LS0_RX, BSSB_LS0_TX |
| I3C | I3C[1:0]_SDA, I3C[1:0]_SCL |
| ISH | ISH_I3C0_SDA, ISH_I3C0_SCL |
