27 / 74 page ![]() STR71xF Introduction 27/74 1. The Reset configuration of the I/O Ports is IPUPD (input pull-up/pull down). Refer to Table 7 on page 28. 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 2. V33IO-PLL and V33 are internally connected. VSSIO-PLL and VSS are internally connected. 1.6 External Connections Figure 5. Recommended External Connection of V18 and V18BKP pins 63 C4 P0.8/U0.RX/U 0.TX I/O pd CT X4mA T Port 0.8 UART0: Receive Data input UART0: Transmit data output. Note: This pin may be used for single wire UART (half duplex) if programmed as Alternate Function Output. The pin will be tri-stated except when UART transmission is in progress 64 A2 P0.9/U0.TX/B OOT.0 I/O pd CT 4mA X X Port 0.9 Select Boot Configuration input UART0: Transmit data output Table 6.
