Table 48. ICSB
0—7
(ESIO Input Channel Start Bit) Registers
Note:
These registers are not directly program-accessible (memory-mapped to addresses 0xE0010—0xE0017).
Table 49. ICSL
0—1
(ESIO Input Channel Sample Length) Registers
Note:
These registers are used only in frame mode (
ICR
[IMODE] = 0) and are not directly program-accessible
(memory-mapped to addresses 0xE0018—0xE0019).
Table 50. ICVV (ESIO Input Channel Valid Vector) Register
Note:
This register is not directly program-accessible (memory-mapped to address 0xE001B). For simple mode,
enable only logical channel 0, i.e., set
ICVV
to 0x0001. For frame mode, the bits in
ICVV
must be packed,
i.e., channels must be allocated from 0 to 15 with no holes between valid channels. For example, if
ICVV
contains 0x00FF, then logical channels 0—7 are enabled and demultiplexed. A value of 0x08FF for
ICVV
is
invalid because the channels are not packed.
