10 / 16 page MT8888C/MT8888C-1 4-100 Table 8 . Status Register Description Figure 12 - MT8888C Interface Connections for Various Intel Micros Figure 13 - Application Circuit (Single-Ended Input) BIT NAME STATUS FLAG SET STATUS FLAG CLEARED b0 IRQ Interrupt has occurred. Bit one (b1) or bit two (b2) is set. Interrupt is inactive. Cleared after Status Register is read. b1 TRANSMIT DATA REGISTER EMPTY (BURST MODE ONLY) Pause duration has terminated and transmitter is ready for new data. Cleared after Status Register is read or when in non-burst mode. b2 RECEIVE DATA REGISTER FULL Valid data is in the Receive Data Register. Cleared after Status Register is read. b3 DELAYED STEERING Set upon the valid detection of the absence of a DTMF signal. Cleared upon the detection of a valid DTMF signal. 8031/8051 8080/8085 MT8888C/MT8888C-1 A8-A15 PO RD WR CS RD WR RS0 D0-D3 A8 IN+ IN- GS VRef VSS OSC1 OSC2 TONE WR CS VDD St/GT ESt D3 D2 D1 D0 IRQ/CP RD RS0 DTMF/CP INPUT DTMF OUTPUT C1 R1 R2 X-tal RL VDD C3 C2 R4 R3 To µP or µC Notes: R1, R2 = 100 k Ω 1% R3 = 374 Ω 1% R4 = 3.3 k Ω 10% RL = 10 k Ω (min.)

The performance of the MT8888C/MT8888C-1 can be optimized by keeping noise on the supply rails to a minimum. The decoupling capacitor (C3) should be connected close to the device and ground loops should be avoided. MT8888C/MT8888C-1 |
