Figure 12-1. Programming Block Diagram
ispJTAG
The ispJTAG pins are standard IEEE 1149.1 TAP (Test Access Port) pins. The ispJTAG pins are dedicated pins and
are always accessible when the MachXO device is powered up.
Table 12-1. ispJTAG Pins Definition
TDO
The Test Data Output pin is used to shift serial test instructions and data out of the MachXO. TDO is clocked out on
the falling edge of TCK. When TDO is not being driven by the internal circuitry, the pin will be in a high impedance
state (tristate). An internal pull-up resistor on the TDO pin is provided. The internal resistor is pulled up to the asso-
ciated V
TDI
The Test Data Input pin is used to shift serial test instructions and data into the MachXO. TDI is clocked into the
device on the rising edge of TCK. An internal pull-up resistor on the TDI pin is provided. The internal resistor is
pulled up to the associated V
TMS
The Test Mode Select pin controls test operations on the TAP controller. On the rising edge of TCK, depending on
the state of TMS, a transition will be made in the TAP controller state machine. An internal pull-up resistor on the
TMS pin is provided. The internal resistor is pulled up to the associated V
