C-bus I/O port with RESET, OE, and INT
7.3.4
IOC0 to IOC4 - I/O Configuration registers
These registers configure the direction of the I/O pins.
Cx[y] = 0: The corresponding port pin is an output.
Cx[y] = 1: The corresponding port pin is an input.
Where ‘x’ refers to the bank number (0 to 4); ‘y’ refers to the bit number (0 to 7).
7.3.5
MSK0 to MSK4 - Mask interrupt registers
These registers mask the interrupt due to a change in the I/O pins configured as inputs. ‘x’
refers to the bank number (0 to 4); ‘y’ refers to the bit number (0 to 7).
Mx[y] = 0: A level change at the I/O will generate an interrupt if IOx_y defined as input
(Cx[y] in IOC register = 1).
Mx[y] = 1: A level change in the input port will not generate an interrupt if IOx_y defined
as input (Cx[y] in IOC register = 1).
7.4 Power-on reset
When power is applied to V
DD
, an internal Power-On Reset (POR) holds the PCA9506 in
a reset condition until V
DD
has reached V
POR
. At that point, the reset condition is released
and the PCA9506 registers and I
2
C-bus state machine will initialize to their default states.
Thereafter, V
DD
must be lowered below 0.2 V to reset the device.
7.5 RESET input
A reset can be accomplished by holding the RESET pin LOW for a minimum of t
w(rst)
. The
PCA9506 registers and I
2
C-bus state machine will be held in their default states until the
RESET input is once again HIGH.
