Table 52 describes the hardware configuration for the MFX interface.
Table 52. Hardware I/O configuration for the MFX interface
I/O Hardware Setting
(1)
Configuration
PC5 SB70 ON
PC5 is connected to MFX as MFX_IRQ_OUT.
No other muxing
PF11 SB60 ON
PF11 is connected to MFX as MFX_WAKEUP.
No other muxing
NRST - ON MCU NRST direct connection.
PB11 SB49 ON
PB11 is used as I2C2_SDA to interface the audio codec, the MFX, the
UCPD, the CTP, the camera, STMod+, and optionally the sensor like the
3D accelerometer and the 3G gyroscope, but also the I
2
C EEPROM and
the external I
2
C connector (SB49 0N).
PB10 SB46 ON
PB10 is used as I2C2_SCL to interface the Audio Codec, the MFX, the
UCPD, the CTP, the Camera, the STMod+, and optionally the sensor like
the 3D accelerometer and the 3G gyroscope, but also the I
2
C EEPROM
and the external I
2
C connector (SB46 ON).
1. The default configuration is shown in bold.
Table 53 describes the hardware I/O driven by the MFX.
