9.0
The module consists of a single SR Latch with multiple
Set and Reset inputs as well as separate latch outputs.
The SR Latch module includes the following features:
• Programmable input selection
• SR Latch output is available internally/externally
• Separate Q and Q outputs
• Firmware Set and Reset
9.1
The latch is a Set-Reset latch that does not depend on a
clock source. Each of the Set and Reset inputs are
active-high. The latch can be Set or Reset by CxOUT,
SRI pin, or variable clock. Additionally the SRPS and the
SRPR bits of the SRCON0 register may be used to Set
or Reset the SR Latch, respectively. The latch is
Reset-dominant, therefore, if both Set and Reset inputs
are high the latch will go to the Reset state. Both the
SRPS and SRPR bits are self resetting which means
that a single write to either of the bits is all that is
necessary to complete a latch Set or Reset operation.

Preliminary
9.2
The SRQEN and SRNQEN bits of the SRCON0 regis-
ter control the Q and Q latch outputs. Both of the SR
latch outputs may be directly output to an I/O pin at the
same time.
The applicable TRIS bit of the corresponding port must
be cleared to enable the port pin output driver.
9.3
Upon any device Reset, the SR latch is not initialized.
The user’s firmware is responsible to initialize the latch
output before enabling it to the output pins.
