eTPU Channel n Status Control Register (ETPU_CnSCR)
ETPU_C
n
SCR is a collection of the interrupt status bits of the channel, and also the function mode
definition (read-write). Bits CIS, CIOS, DTRS, and DTROS for each channel can also be accessed from
ETPU_CISR, ETPU_CIOSR, ETPU_CDTRSR, and ETPU_CDTROSR respectively. For more
information on the three previously mentioned registers, refer to the eTPU reference manual.
NOTE
The MPC5553/MPC5554 core must write 1 to clear a status bit.
NOTE
In the MPC5554, eTPU A channels [0:2,12:15,28:29] and eTPU B channels
[0:3,12:15,28:31] are connected to the DMA; in the MPC5553, eTPU A
channels [0:2, 14:15] are DMA connected. The data transfer request lines
that are not connected to the DMA controller are left disconnected and do
not generate transfer requests, even if their request status bits assert in
registers ETPU_CDTRSR and ETPU_C

CPBA
[0:10]
Channel n parameter base address. The value of this field multiplied by 8 specifies the
SDM parameter base host (byte) address for channel n (2-parameter granularity).
The formula for calculating the absolute channel parameter base (byte) address, as seen
by the host, is eTP CPBA*8. The SDM is mirrored in the parameter
sign extension (PSE) area. The formula to calculate the absolute channel parameter base
(byte) address in the PSE area is eTP CPBA*8.
For more information on SDM addresses, refer to the eTPU reference manual.
