MT9076
Preliminary Information
Per Time Slot Control word bit 1 "RPSIG" is set low, CSTi is used to control the transmit channel associated
signaling. The DSTi and DSTo streams contain the transmit and receive voice and digital data.
Only 30 of the 32 ST-BUS channels are used for each of DSTi, DSTo, CSTi and CSTo. In each case individual
channel mapping is as illustrated in Table 10 Time slot to Channel Relationship.
5.0 Reset Operation (Initialization)
The MT9076 can be reset using the hardware RESET pin (pin 11 in PLCC, pin 64 in LQFP) or the software
reset bit RST (page 1H, address 1AH) . When the device emerges from its reset state it will begin to function
with the default settings described in Table 14 (T1) and Table 15 (E1). All control registers are set to 00H. A
reset operation takes 1 full frame (125 us) to complete.
