iC-MD 48-BIT QUADRATURE COUNTE^pR^reliminary
WITH RS422 RECEIVER AND SPI/BISS INTERFACE
COMMUNICATION CONTROL
Rev B1, Page 17/30
iC-MD can communicate simultaneously via SPI and
BiSS in order to exchange data between SPI and BiSS.
For this purpose, SPI writes the data to be read by BiSS
in the AB register, and BiSS reads the SPICH (BiSS
channel 0 configured as SPICH, see table 65).
ABRES2
Code
1
Addr. 0x30; bit 2
Function
Reset of counter 2
Default = 0b0
Table 39: Reset Counter 2
If both interfaces attempt to read or write at the same
time a different RAM address than the SPICH (Adr.
0x20 to 0x25), then the bit error COMCOL (table 54)
is set and the communication of the interface without
priority (see table 71) is not valid.

Addr. 0x30; bit 4
Default = 0b0
Function
Load TP2 with TP1 value
and TP1 with ABCNT value
Counter must be configured to 24 bit length
Register address 0x30 contains the write only instruc-
tion byte. When one of these bits is set to 1, then the
corresponding operation is executed and then set back
to 0, excepts the bits ACT0 and ACT1 which remain to
the written value.
Table 41: Touch Probe Instruction
The instruction bits ACT0 and ACT1 set the actuator
pins ACT0 and ACT1 to high or low voltage.
