T7531A/T7536 16-Channel Programmable
Software Interface
Table 18 lists the RAM data space for the DSP engine. Space for up to 16 channels is allocated. The total T7531A
RAM size is 2 Kwords, arranged as 2 x 1 Kbanks. Address bit 15 is used as a read/write flag (1 = read). The micro-
processor interface can read any address in the DSP engine RAM space.
Table 18. DSP Engine RAM Memory Map
1. The receive and transmit ac routine addresses are the only addresses that can address ROM code.
2. For time slots 1—15, the address shown is the first address. Refer to time slot 0 for range information.
