Important Notes
1. SDIO_HOST_D1
This signal is muxed with WAKE_3, which is transition configurable. To
trigger an interrupt, the designer must map WAKE_3 signal to a dedicated
GPIO. The pulse on GPIO must be long enough (typically 8 ms) to be
detected in any mode.
This feature might not be activated in the software release preloaded in the
module. Please contact Sequans technical support if you intend to use it.
2. USB_EXT_VBUSVLD
This signal is muxed with WAKE_2, which is transition configurable. To
trigger an interrupt, the designer must map WAKE_2 signal to a dedicated
GPIO. The pulse on GPIO must be long enough (typically 8 ms) to be
detected in any mode.
This feature might not be activated in the software release preloaded in the
module. Please contact Sequans technical support if you intend to use it.
3. WAKE_0
a) As default software configuration, WAKE_0 detects a low level to
wake-up the baseband; this behavior can be changed by software. To
trigger an interrupt, the designer must map WAKE_0 signal to a dedi-
cated GPIO. The pulse on GPIO must be long enough (typically 8 ms)
to be detected in any mode. Please refer to Module Integration Guide
or Sequans Technical Support for more detail.
b) Extra current leakage occurs when WAKE_0 is high and the module in
low power mode. It is then recommended to introduce a tiny logic
inverter gate in front of WAKE_0 when WAKE_0 is high in low-power
mode; you can also consider to use WAKE_1 if possible. The extra
current leakage does not occur when WAKE_0 is low when the module
is in low power mode (wake on level high).
4. WAKE_1
As default software configuration, WAKE_1 detects a low level to wake-up
the baseband; this behavior can be changed by software.
This feature might not be activated in the software release preloaded in the
module. Please contact Sequans technical support if you intend to use it.
