PCA9634
8-bit Fm+ I 2 C-bus LED driver
7.1.2 LED All Call I 2 C-bus address
? Default power-up value (ALLCALLADR register): E0h or 1110 000X
? Programmable through I 2 C-bus (volatile programming)
? At power-up, LED All Call I 2 C-bus address is enabled. PCA9634 sends an ACK when
E0h (R/W = 0) or E1h (R/W = 1) is sent by the master.
See Section 7.3.8 “ALLCALLADR: LED All Call I 2 C-bus address” for more detail.
Remark: The default LED All Call I 2 C-bus address (E0h or 1110 000X) must not be used
as a regular I 2 C-bus slave address since this address is enabled at power-up. All the
PCA9634s on the I 2 C-bus will acknowledge the address if sent by the I 2 C-bus master.
7.1.3 LED Sub Call I 2 C-bus addresses
? 3 different I 2 C-bus addresses can be used
? Default power-up values:
– SUBADR1 register: E2h or 1110 001X
– SUBADR2 register: E4h or 1110 010X
– SUBADR3 register: E8h or 1110 100X
? Programmable through I 2 C-bus (volatile programming)
? At power-up, Sub Call I 2 C-bus addresses are disabled. PCA9634 does not send an
ACK when E2h (R/W = 0) or E3h (R/W = 1), E4h (R/W = 0) or E5h (R/W = 1), or
E8h (R/W = 0) or E9h (R/W = 1) is sent by the master.
See Section 7.3.7 “SUBADR1 to SUBADR3: I 2 C-bus subaddress 1 to 3” for more detail.
Remark: The default LED Sub Call I 2 C-bus addresses may be used as regular I 2 C-bus
slave addresses as long as they are disabled.
7.1.4 Software Reset I 2 C-bus address
The address shown in Figure 6 is used when a reset of the PCA9634 needs to be
performed by the master. The Software Reset address (SWRST Call) must be used with
R/W = 0. If R/W = 1, the PCA9634 does not acknowledge the SWRST. See Section 7.6
“Software Reset” for more detail.

Software Reset address
Remark: The Software Reset I 2 C-bus address is a reserved address and cannot be used
as a regular I 2 C-bus slave address or as an LED All Call or LED Sub Call address.
