SAA7114H
Notes
1. In accordance with the
“IEEE1149.1” standard the pads TDI, TMS, TCK and TRST are input pads with an internal
pull-up transistor and TDO is a 3-state output pad.
2. Pin strapping is done by connecting the pin to supply via a 3.3 k
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).
3. Pin RTCO: operates as I2C-bus slave address pin; RTCO = 0 slave address 42H/43H (default); RTCO = 1 slave
address 40H/41H.
4. Pin ALRCLK: 0 = 24.576 MHz crystal (default); 1 = 32.110 MHz crystal.
5. For board design without boundary scan implementation connect the TRST pin to ground.
6. This pin provides easy initialization of the Boundary Scan Test (BST) circuit. TRST can be used to force the Test
Access Port (TAP) controller to the TEST_LOGIC_RESET state (normal operation) at once.
