Pump Configuration
3.6.1
Pump Configuration Setup (Host
ISAR)
The pump is configured by the host. The Host Interrupt Status register (HIS) indicates that a new
pump configuration is available in the mailbox registers.
Important note:
It is important to note that configuration of the pump will reset the whole data path except buffer
configuration, i.e. any configuration of the SART and IOM-2 is invalid, therefore the pump should be
configured right after buffer configuration and precede SART and IOM-2 configuration.
The LSB of the control register holds the number of additional parameter words which are passed via
the mailbox . The maximum number N of parameter words depends on the pump path mode.
The message coding of configuration setup for some of the pump modes is similar in a few of the
parameters, however the total message coding is described separately for each of the pump modes
which are:
Pump Mode
PMOD
Fax modulations
Datamodem modulations
Halfduplex modulations
V.110
DTMF
DTMF transmission
Bypass
001
010
011
100
101
110
111
As the modulation based pump modes (001, 010, 011) are not available in datapath 2 , the second
channel must not be configured to these pump modes.
The table below shows to which of the pump modes datapath 2 can be configured.
Datapath 1 (DPS=01)
Datapath 2 (DPS=10)
Fax modulations
Datamodem modulations
Halfduplex modulations
V.110
DTMF
DTMF transmission
Bypass
V.110 (see note)
Bypass
Important note:
It is important to note that datapath 2 must not be configured to V.110 if path 1 is configured to
datamodem modulations at the same time.
