Reserved bits.
The write access is ignored. The read value of these bits is always "0".
Number of channel of sub frame 1 is set.
This is valid only when the frame is 2 sub frame construction (SBFN of CNTREG is "1"),
and is invalid when the frame is 1 sub frame construction (SBFN of CNTREG is "0".)
Up to 32 channels are able to be specified, and S1CHN needs to be set to "number of
channel – 1".
Example 1 S1CHN = "00011": Sub frame 1 becomes 4 channel construction
Example 2 S1CHN = "11111": Sub frame 1 becomes 32 channel construction
S1WDL is valid only in 2 sub frame construction (SBFN of CNTREG is "1") and is invalid
in 1 sub frame construction (SBFN of CNTREG is "0".)
Channel length of the channel constructing sub frame 1 (bit length of channel) is set.
7 - 32 bit of channel length are available but 1 - 6 bit are prohibited. S1CHN needs to
be set to "number of channel – 1".
Example 1 S1CHL = "00110": Channel length becomes 7 bit
Example 2 S1CHL = "11111": Channel length becomes 32 bit
Channel length is able to be set to 32 or less regardless of RHLL value of CNTREG
register.
S1WDL is valid only in 2 sub frame construction (SBFN of CNTREG is "1") and is invalid
in 1 sub frame construction (SBFN of CNTREG is "0".)
Word length of the channel constructing sub frame 1 (bit length of channel) is set.
7 - 32 bit of word length are available but 1 - 6 bit are prohibited. S1WDL needs to be
set to "word length – 1".
Example 1 S1WDL = "00110": Word length becomes 7 bit
Example 2 S1WDL = "11111": Word length becomes 32 bit
RHLL of CNTREG register is "1": Set word length to 16 or less and channel length to
shorter than the one set to S1CHL
RHLL of CNTREG register is "0": Set word length to 32 or less and channel length to
shorter than the one set to S1CHL
S1WDL is valid only in 2 sub frame construction (SBFN of CNTREG is "1") and is invalid
in 1 sub frame construction (SBFN of CNTREG is "0".)
Reserved bits.
The write access is ignored. The read value of these bits is always "0".
Number of channel of sub frame 0 is set up to 32 channels.
S0CHN needs to be set to "number of channel – 1".
Example 1 S0CHN = "00011": Sub frame 0 becomes 4 channel construction
Example 2 S0CHN = "11111": Sub frame 0 becomes 32 channel construction
