Note 1 on LED Support
WL_LED_ACT Implementation on the SSD30AG or MSD30AG –
-
WL_LED_ACT has an internal pull-down, and thus is low when the radio is off (not powered).
Note: The SSD30AG and MSD30AG devices require the SD30AG driver release 3.3.3 and greater.
Driver control implementation (when enabled) –
-
WL_LED_ACT is set to VDDIO when the radio is associated to an AP.
-
WL_LED_ACT is set low at all other times (not associated).
Note 2:
If the following lines are available on the radio you are integrating into your system, you must
connect and control them with the host device.
CHIP_PWD_L
SYS_RST_L
BT_RST_L
VDDIO_DR
If the radio stays powered up and the host goes down or is reset, communications cannot be re-
established with the radio. The host SDIO controller must re-establish communication with the radio
by reloading the radio firmware after a power-on or a reset.
