Notes
1. Pin type: I = input, O = output, S = supply, pu = pull-up.
2. For board design without boundary scan implementation connect TRSTe and TRSTd to ground.
3. This pin provides easy initialization of the Boundary Scan Test (BST) circuit. TRSTe and TRSTd can be used to force
the Test Access Port (TAP) controller to the TEST_LOGIC_RESET state (normal operation) at once.
4. In accordance with the “IEEE1149.1” standard the pads TDIe (TDId), TMSe (TMSd), TCKe (TCKd) and TRSTe
(TRSTd) are input pads with an internal pull-up resistor and TDOe (TDOd) is a 3-state output pad.
5. Pin strapping is done by connecting the pin to supply via a 3.3 kΩ resistor. During the power-up reset sequence the
corresponding pins are switched to input mode to read the strapping level. For the default setting no strapping
resistor is necessary (internal pull-down).
6. Pin ALRCLK: 0 = 24.576 MHz crystal (default); 1 = 32.110 MHz crystal.
7. Pin RTCO: operates as I2C-bus slave address pin; RTCO = 0 slave address 42H/43H (default); RTCO = 1 slave
address 40H/41H.
