Freescale Semiconductor 25-7
25.2.1.9 Test Data Input (TDI)
The TDI pin receives serial test instruction and data. TDI is sampled on the rising edge of TCK.
25.2.1.10 Test Mode Select (TMS)
The TMS pin is used to sequence the IEEE
®
1149.1-2001 TAP controller state machine. TMS is sampled
on the rising edge of TCK.
25.3 Memory Map
The NDI block contains no memory mapped registers. Nexus registers are accessed by the development
tool via the JTAG port using a register index and a client select value. The client select is controlled by
loading the correct access instruction into the JTAG controller; refer to
Table 25-4 . OnCE registers are
accessed by loading the appropriate value in the RS[0:6] field of the OnCE command register (OCMD)
via the JTAG port.
Table 25-2 shows the NDI registers by Client Source ID and Index values.
