Module: MSSP - SPI mode
The SDI pin is controlled by the module and not by
the state of the TRIS bit. This means that the SDI
pin cannot be an output when the MSSP module is
in SPI mode.

Module: Electrical Specifications
The Supply Voltage specification has not yet met
the design target (Data Sheet specification). The
specification for these devices is shown in Table 1.
Module: A/D Specifications
The Offset Error specification has not yet met the
design target (Data Sheet specification). The
specification for these devices is shown in Table 1.
Module: TMR1
When operating in external clock mode (TMR1CS
is set), reading either of the timer 1 registers
(TMR1H or TMR1L) may cause the timer not to
increment as expected. This occurs for both syn-
chronous and asynchronous inputs.

Work Around
Do not read either the TMR1H or the TMR1L reg-
isters when operating in external clock mode
(TMR1CS is set). If the application needs to read
the 16-bit counter, evaluate if this function can be
moved to the TMR0 or one of the other timer
resources on the device.
