RCP- Interface
9.1.6
The controller can be interrupted via the RCP Interface (IC23,PIN 32). The
Interrupt use depends on the selected Mode: To modulate the H0 field with a
Homospoil curve (Z-Gradient), to set the Lock in LockHold condition (Regulator
switched off, no Delta Sweep) or to set LockON (Regulator on). For all conditions
the raising or falling of an edge generates an interrupt. The signals are galvanically
separated with an Optocoupler (IC8). A transistor switch T1 drives the Optocoupler
so that the Bruker norm for threshold switching is adhered to (Logic High = 1
Bruker Volt).
DSP- Host Interface
9.1.7
Communication between the DSP IC18 and the Microcontroller IC23 is achieved
with 8 Data Bits, three Address Connections and three Control Connections. The
controller has the Host Interface Register mapped in its Data Memory (from
Address 9000h). DSP is selected with DSP_HEN
~
. The controller chooses the type
of access to the DSP with the DSP_HR/W
~
. The DSP can cause an Interrupt on the
controller at any time (DSP_HREQ
~
, IC23 Pin 24).
After each Power Up or Reset the DSP applications software is loaded via the DSP
Host Interface. The DSP keeps its program in the Static RAM IC19.
DSP-Section (Hardware)
9.1.8
The DSP operates in Bootstrap mode. The mode is read in after the Reset with the
Pins MODA and MODB. The DSP connection D23 is grounded with a 10k Resistor.
This leads to the internal Bootstrap Program being activated in DSP after a Reset
and the program being loaded via the Host Interface. The data from the Receiver
(Dispersion, Absorption and external Field sensor signals) are read into the DSP via
the serial sychronized SSI Interface. The display data are sent via the SSI Interface
to the graphic terminal (GT01 board in the X32). The entire DSP program is
synchronized with the RP1_C pulse via the Interrupt B (negative Edge). External
memory MCM56824 (8k*24) is connected at Port A.
The Decoder consists of a 15ns PAL 20L8. The ME
~
Signal is decoded here for the
memory. The Signals EDAC1
~
and EDAC2
~
write the data to the Latches
(74ACT534 IC12, IC15). The WR
~
signal can’t be decoded by the PAL (due to time
considerations) and are therefore decoded by fast AC Gates (47AC032). The Most
Significant Bit (MSB) is inverted because the DSP delivers the data in two
complementing formats (CTC) and the D/A converter also requires the
Complementary Offset Binary Format (COB). The converter has its own special 5 V
analog supply (to reduce disturbance in the converter). The Grounds HO_GND and
DGND are connected at DAC (IC17).
