PCA9621
65 mA 8-bit 2-wire bus output port
7.6 A0, A1, A2 — address lines
The slave address of the PCA9621 is shown in Figure 4. The address pins (A2, A1, A0)
must be driven to a HIGH or LOW level—they are not internally pulled to a default state.
The read/write bit must be set LOW to enable a write to the Control register, or HIGH to
read from the Control register.
7.7 Control register
The Control register of the PCA9621 is shown in Figure 5. Each of the four output ports
can be activated independently by setting the appropriate bit in the Control register.
A LOW or ‘zero’ bit indicates that the respective channel (P7 to P0) is disabled
(high-impedance). The default reset condition of the register is all zeros, all ports
high-impedance. A HIGH or ‘one’ bit indicates the respective channel is active (sinking).
Example: Programming C1h (1100 0001b) into the Control register results in ports P0, P6
and P7 being ON (sinking) and the remaining ports being OFF (high-impedance).
