The TMS Header is clocked into the device to
select the Shift DR state.
The input value of the PrAcc bit, which is ‘0’, is
clocked in.
XferFastData Pseudo Operation
For 2-wire (4-phase) – on the last clock,
the oPrAcc bit is shifted out on TDO while
clocking in the TMS Header. If the value of
oPrAcc is not ‘1’, the whole operation must
be repeated.
For 2-wire (4-phase) – the TDO during this
operation will be the LSb of output data.
The rest of the 31 bits of the input data are
clocked in and the 31 bits of output data
are clocked out. For the last bit of the input
data, the TMS Footer = 1 is set.

EXAMPLE 6-1:
// Select the Fastdata Register
SendCommand(ETAP_FASTDATA)
// Send/Receive 32-bit Data
oData = XferFastData(32’h12)
The SendCommand (ETAP_FASTDATA) must be sent
first to select the Fastdata register, as shown in
Example 6-1. See Table 19-4 for a detailed descriptions
of commands.
Note:
TMS Footer = 10 is clocked in to return the TAP
controller to the Run/Test Idle state.
The 2-Phase XferData is only used when
talking to the PE. See 16.0 “The Pro-
gramming
information.
