Enhanced Time Processing Unit (eTPU2)
Table 24-33. ETPU_CxCR field description
Field Description
21-31 CPBA[10:0]—Channel x Parameter Base Address
The value of this field times 8 specifies the SPRAM parameter base host (byte) address for channel x
(2-parameter granularity; see Section 24.5.2.4, SPRAM organization). As seen by the Host, the channel
parameter base (byte) address is:
without parameter sign extension: ETPU_Base + 0x8000 + CPBA*8
with parameter sign extension: ETPU_Base + 0xC000 + CPBA*8
Note: The fields ETCS, CFS and CPBA must only be changed while the channel is disabled (field
CPR = 00).
