Table 60. OCSB
0—7
(ESIO Output Channel Start Bit) Registers
Note:
These registers are not directly program-accessible (memory-mapped at address 0xE0030 to 0xE0037).
Table 61. OCSL
0—1
(ESIO Output Channel Sample Length) Registers
Note:
These registers are used only in frame mode (
OCR
[OMODE] = 0) and are not directly program-accessible
(memory-mapped to addresses 0xE0038 and 0xE0039).

Table 62. OCVV (ESIO Output Channel Valid Vector) Register
Note:
This register is not directly program-accessible (memory-mapped to address 0xE003B). For simple mode,
enable only logical channel 0, i.e., set
OCVV
to 0x0001. For frame mode, the bits in
OCVV
must be packed,
i.e., channels must be allocated from 0 to 15 with no holes between valid channels. For example, if
OCVV
contains 0x00FF, then logical channels 0—7 are enabled and demultiplexed. A value of 0x08FF for
OCVV
is
invalid because the channels are not packed.
