Long Transfer Count with Package Transfer
The features of the C16x PEC functions are expanded by long transfer counts and
package transfers, where a package is a container with always the same defined number
of bytes or words. If enabled by the PT flag in PECCx, each service request initiates an
entire package of data to be transferred by the PEC channel. The length of data
packages is determined by the PEC Transfer COUNT in the PECCx register, the amount
of package transfers is defined by the long 16-bit transfer count COUNT2 in the new
PECXCx register. In PT mode, packages of up to 256 bytes or words are supported.
The PEC transfer COUNT2 allows to service up to 64K transfer requests by the
respective PEC channel, and then (when COUNT2 reaches 00H) activate the interrupt
service routine in the CPU as known from standard PEC channels. After each PEC
package transfer the COUNT2 field is decremented by one and the request flag is
cleared to indicate that the request has been serviced. Note: Within a package transfer
only every second machine cycle is a PEC transfer cycle.
Note: In INCA-D, the package length is limited to 1 transfer (COUNT field must be 01
Note: The PT mode is available for two PEC channels: PECC2 and PECC0. These two

Therefore only the long transfer count COUNT2 which enables block lengths of up
to 64K transfers, is available in Package Transfer mode (the PT flag is set in
PECCx register). Package transfers with COUNT>1 are not supported.
channels with long transfer counts can also be used in Channel Link Mode (see
below), to be concatenated with channel 3 and channel 1.
