7 / 50 page  NXP Semiconductors PCA8561 Automotive 18 × 4 LCD segment driver aaa-012345 address counter 00h auto-increment 01h 02h 03h ... 0Dh 0Eh 0Fh Figure 5. Address counter incrementing 7.2 Command registers of the PCA8561 7.2.1 Command: Device_ctrl The Device_ctrl command sets the device into a defined state. It should be executed before enabling the display (see bit DE in Table 6). Bit Symbol Value Description 7 to 5 - 000 default value frame frequency selection 000 ffr = 32 Hz 001[1] ffr = 64 Hz 010 ffr = 96 Hz 011 ffr = 128 Hz 100 ffr = 160 Hz 101 ffr = 192 Hz 110 ffr = 224 Hz 4 to 2 FF[2:0] 111 ffr = 256 Hz internal oscillator control 0[1] enabled 1 OSC 1 disabled clock output enable 0[1] clock signal not available on pin CLK; pin CLK is in 3-state 0 COE 1 clock signal available on pin CLK Table 5. Device_ctrl - device control command register (address 01h) bit description [1] Default value. 7.2.1.1 Internal oscillator and clock output Bit OSC enables or disables the internal oscillator. When the internal oscillator is used, bit COE allows making the clock signal available on pin CLK.
