link interrupt condition of linked PEC channels (A and B channels) which requires
support from the CPU. The following channel link interrupt conditions requesting CPU
service are possible:
• In single transfer mode a COUNT value change from 01
H
to 00
H
in a linked PEC
channel and CL flag is set in the respective PEC control register.
In this case the CPU service is requested to update the PEC control and pointer registers
while the next block transfer is executed (the whole transfer is divided into separately
controlled block transfers). The last block transfer is determined by the missing link bit in
the new (linked) PEC control register. If a new service request hits a linked channel with
count equal to zero and channel link flag disabled, a standard interrupt, as known from
standard PEC channels, is performed.
The channel link interrupt subnode register CLISNC is defined as follows:
CLISNC Reset
Value:
0000
H
The source and destination pointers
specifiy the locations between which the data is
to be moved. PEC transfers can be performed between any locations in the entire
memory space of the M2. For each of the 8 PEC channels, the source and destination
addresses are specified by a 8-bit segment number and a 16-bit offset. The source and
destination segment numbers, respectively PECSSN and PECDSN, are stored in a SFR
associated with each channel (PECSNx, see description below). The offset pointers for
the source and destination address do not reside in specific SFRs, but are mapped into
the internal RAM of the M2 just below the bit-addressable area (see
Figure 5-2
).
Bit
Function
xxIE
PEC Channel Link Interrupt Enable Control Bit
(individually enables/disables a specific channel pair interrupt request)
‘0’:
PEC interrupt request is disabled
‘1’:
PEC interrupt request is enabled
xxIR
PEC Channel Service Request Flag
‘0’:
No channel link service request pending
‘1’:
This source (channel pair) has raised an request to service a PEC
channel after channel linking
