EXTEST:
INTEST:
SAMPLE/PRELOAD: Provides a snap-shot of the pin level during normal operation, or
ICODE:
TAP_TEST1 39 bit field for selecting operation
TAP_TEST2: Wait for Level Metering result ready (should be > t.b.d. mS)
TAP_TEST5: Level Metering Data output (1 bit result of Level Metering per channel)
TAP_TEST4: Level Metering Operation is switched off

Is used to examine the board interconnections.
Supports internal chip testing (is the default value of the instruction
register)
is used to preload the boundary scan with a test vector
The 32 bit identification register is serially read out via TDO. It contains a
version number (4 bit), a device code (16 bit) and the manufacture code
(11 bit). The LSB is fixed to ‘1’.
For the SICOFI-4 V2.2 and V2.3 the Code is:
‘0011 0000 0000 0001 0101 0000 1000 001 1’
(Level Metering Offset, Loops, Tone Generator )
A bit entering TDI is shifted to TDO after one TCK clock cycle
