Communication Processor Module
16.7.6.2.1 IDL Interface Programming Example. Using the example in
Section 16.7.6.1 IDL Interface Implementation as a base model, the initialization
sequence is as follows:
1. Assuming SMC1 is connected to the B1 channel, SMC2 is connected to the B2
2. The SIMODE equals 0x80008145. Only TDMA is used. The two SMCs are connected
3. The SICR equals 0x0000c000. SCC2 is connected to the time-slot assigner. SCC2
4. In the PAODR, bit 9 is set to 1. Configure L1TXDA to be an open-drain output.
5. In the PAPAR, bits 9, 8, and 7 are set to 1. Configure L1TXDA, L1RXDA, and
6. In the PADIR, bits 9 and 8 are set to 1. PADIR bit 7 = 0. Configure L1TXDA, L1RXDA,
7. In the PCPAR, bits 12, 5, and 11 are set to 1. Configure L1RQa, L1TSYNCa, and
8. In the PCDIR, bit 12 is set to 0. L1RQA is an input. L1TSYNCA performs the L1GRA
9. TheSIGMR equals 0x04. Enable TDMA (one static TDM).
