STR710 pin description
1. The Reset configuration of the I/O Ports is IPUPD (input pull-up/pull down). Refer to
2. In reset state, these pins configured as Input PU/PD with weak pull-up enabled. They must be configured
3. In reset state, these pins configured as Input PU/PD with weak pull-down enabled to output Address
4. V
5. During the reset phase, these pins are in input pull-up state. When reset is released, they are configured as
6. During the reset phase, these pins are in input pull-up state. When reset is released, they are configured as
7. During the reset phase, these pins are in input pull-down state. When reset is released, they are configured
8. During the reset phase, this pin is in input floating state. When reset is released, it is configured as Output
Pin name
The Port bit configuration at reset is PC0=1, PC1=1, PC2=0. The port data register bit (PD) value depends
on the pu/pd column which specifies whether the pull-up or pull-down is enabled at reset
