PRODUCTION DATA.
Table 5-14 shows the GPIO pins used by each peripheral bootloader. This device supports two sets of GPIOs for each mode, as shown in Table 5-14.
BOOTLOADER | GPIO PINS | NOTES |
---|---|---|
SCI-Boot0 | SCITXDA: GPIO84
SCIRXDA: GPIO85 |
SCIA Boot I/O option 1 (default SCI option when chosen through Boot Mode GPIOs) |
SCI-Boot1 | SCITXDA: GPIO28
SCIRXDA: GPIO29 |
SCIA Boot option 2 – with alternate I/Os. |
Parallel Boot | D0 – GPIO65
D1 – GPIO64 D2 – GPIO58 D3 – GPIO59 D4 – GPIO60 D5 – GPIO61 D6 – GPIO62 D7 – GPIO63 HOST_CTRL – GPIO70 DSP_CTRL – GPIO69 |
|
CAN-Boot0 | CANRXA: GPIO70
CANTXA: GPIO71 |
CAN-A Boot – I/O option 1 |
CAN-Boot1 | CANRXA: GPIO62
CANTXA: GPIO63 |
CAN-A Boot – I/O option 2 |
I2C-Boot0 | SDAA: GPIO91
SCLA: GPIO92 |
I2CA Boot – I/O option 1 |
I2C-Boot1 | SDAA: GPIO32
SCLA: GPIO33 |
I2CA Boot – I/O option 2 |
SPI-Boot0 | SPISIMOA - GPIO58
SPISOMIA - GPIO59 SPICLKA - GPIO60 SPISTEA - GPIO61 |
SPIA Boot – I/O option 1 |
SPI-Boot1 | SPISIMOA – GPIO16

SPIA Boot – I/O option 2 |
USB Boot | USB0DM - GPIO42
USB0DP - GPIO43 |
The USB Bootloader will switch the clock source to the external crystal oscillator (X1 and X2 pins). A 20-MHz crystal should be present on the board if this boot mode is selected. |
