BDR Register Bit 7 6 5 4 3 2 1 0 Name — — — — — — BEEP1 BEEP0 R/W — — — — — — R/W R/W POR — — — — — — 0 0 Bit7~6 unimplemented, read as "0" Bit 1 BEEP1: output signal 0: low 1: high When BEEP1 Function is useful, if Audio Processor souce is selected beep1, the Beep 1 pad is connect to Audio Processor Bit 0 BEEP0: output signal 0: low 1: high When BEEP0 Function is useful, if speak souce is selected beep0, the Beep 0 pad is connect to speak. The two bits are output pin signals, set or clear BDR data can modify beep0/beep1 status. If the two functions are not useful, modify beep0/beep1 data are not affected beep1/0 pad status. |
