RDM1–RDM0—RAM Division Mode
7.8.5.2 SI MODE REGISTER (SIMODE). The 32-bit SIMODE defines the SI operation
modes. This register allows the user (in conjunction with the SI RAM) to support any or all
of the ISDN channels independently when in IDL or GCI (IOM-2) mode. Any extra SCC
channel can then be used for other purposes in NMSI mode. SIMODE appears to the user
as a memory-mapped, read-write register and is cleared at reset.

These bits define the RAM division mode and the number of multiplexed channels sup-
ported in the SI.
0 = Channel b is disabled. The SI RAMs and TDM routing are in a state of reset, but
1 = The SI is enabled.
0 = Channel a is disabled. The SI RAMs and TDM routing are in a state of reset, but
1 = The SI is enabled.
00 = The SI supports one TDM channel with 64 entries for receive routing and 64 en-
01 = The SI supports one TDM channel with 32 entries for receive routing and 32 en-
10 = The SI supports two TDM channels with 32 entries for the receive routing and 32
11 = The SI supports two TDM channels with 16 entries for receive routing and 16 en-
0 = NMSI mode. The clock source is determined by the SMCxCS bit, and the data
1 = SMCx is connected to the multiplexed SI (TDM channel).
