72 / 116 page  AD9554 Data Sheet Rev. D | Page 72 of 116 GENERAL CONFIGURATION (REGISTER 0x0100 TO REGISTER 0x010E) Multifunction Pin Control (M0 to M9) and Watchdog Timer Table 40. Multifunction Pins (M0 to M9) Control Address Bits Bit Name Description 0x0100 [7:6] M3 driver mode, Bits[1:0] 00 (default) = active high CMOS. 01 = active low CMOS. 10 = open-drain PMOS (requires an external pull-down resistor). 11 = open-drain NMOS (requires an external pull-up resistor). [5:4] M2 driver mode, Bits[1:0] The settings of these bits are identical to Register 0x0100, Bits[7:6]. [3:2] M1 driver mode, Bits[1:0] The settings of these bits are identical to Register 0x0100, Bits[7:6]. [1:0] M0 driver mode, Bits[1:0] The settings of these bits are identical to Register 0x0100, Bits[7:6]. 0x0101 [7:6] M7 driver mode, Bits[1:0] The settings of these bits are identical to Register 0x0100, Bits[7:6]. [5:4] M6 driver mode, Bits[1:0] The settings of these bits are identical to Register 0x0100, Bits[7:6]. [3:2] M5 driver mode, Bits[1:0] The settings of these bits are identical to Register 0x0100, Bits[7:6]. [1:0] M4 driver mode, Bits[1:0] The settings of these bits are identical to Register 0x0100, Bits[7:6]. 0x0102 [7:4] Reserved Reserved. [3:2] M9 driver mode, Bits[1:0] The settings of these bits are identical to Register 0x0100, Bits[7:6]. [1:0] M8 driver mode, Bits[1:0] The settings of these bits are identical to Register 0x0100, Bits[7:6]. 0x0103 7 M0 output/input Input/output control for M0 pin. 0 (default) = input (control pin). 1 = output (status pin). [6:0] M0 function, Bits[6:0] These bits control the function of the M0 pin. See Table 154 and Table 155 for details about the input and output functions that are available.
