Control and Indication I/O Pins
I/O pins P0_0, P0_5, P1_7, P3_1, P3_2, P3_3, P3_4 and P3_7 are configurable control and
indication I/O. Control signals are input to the BM78. Indication signals are output from the BM78.
Table 4‐1 shows configurable I/O pin assignment to control and indication signals.
Note: that RTS can only be assigned to P0_0 and CTS is assigned to P1_7.
Configuring the BM78 can reference the “Application Note_IS1678S_Draft.docx” and
IS1678S Command Set v0 97 20140924.docx.”
