PCA9632

4-bit Fm+ I 2 C-bus low power LED driver

Once subaddresses have been programmed to their right values, SUBx bits need to be

set to 1 in order to have the device acknowledging these addresses (MODE1 register).

Only the 7 MSBs representing the I 2 C-bus subaddress are valid. The LSB in SUBADRx

register is a read-only bit (0).

When SUBx is set to 1, the corresponding I 2 C-bus subaddress can be used during either

an I 2 C-bus read or write sequence.

The LED All Call I 2 C-bus address allows all the PCA9632s in the bus to be programmed

at the same time (ALLCALL bit in register MODE1 must be equal to 1, power-up default

state). This address is programmable through the I 2 C-bus and can be used during either

an I 2 C-bus read or write sequence. The register address can be programmed as a

sub call.

Only the 7 MSBs representing the All Call I 2 C-bus address are valid. The LSB in

ALLCALLADR register is a read-only bit (0).

If ALLCALL bit = 0, the device does not acknowledge the address programmed in register

ALLCALLADR.

7.4 Power-on reset

When power is applied to V DD , an internal power-on reset holds the PCA9632 in a reset

condition until V DD has reached V POR . At this point, the reset condition is released and the

PCA9632 registers and I 2 C-bus state machine are initialized to their default states (all

zeroes) causing all the channels to be deselected. Thereafter, V DD must be lowered below

0.2 V to reset the device.

7.5 Software reset

The Software Reset Call (SWRST Call) allows all the devices in the I 2 C-bus to be reset to

the power-up state value through a specific formatted I 2 C-bus command. To be performed

correctly, it implies that the I 2 C-bus is functional and that there is no device hanging the

bus.

The SWRST Call function is defined as the following:

1. A START command is sent by the I 2 C-bus master.

2. The reserved SWRST I 2 C-bus address ‘0000 011’ with the R/W bit set to 0 (write) is

sent by the I 2 C-bus master.

3. The PCA9632 device(s) acknowledge(s) after seeing the SWRST Call address

‘0000 0110’ (06h) only. If the R/W bit is set to 1 (read), no acknowledge is returned to

the I 2 C-bus master.
