Clarifications/Corrections to the Data
Sheet:
In the Device Data Sheet (DS30605C), the following
clarifications and corrections should be noted:

In Section 10.2 (“SPI Mode”), Figure 10-1 and the
note box immediately following it have been
amended to better demonstrate the peripheral OE
line of the SSP module and describe its
relationship to the TRISC<5> bit of PORTC.
Changes are indicated in bold.

the state of the SS pin can affect the state
read back from the TRISC<5> bit. The
peripheral OE signal from the SSP module
into PORTC controls the state that is read
back
Section 5.3 for information on PORTC). If
read-modify-write instructions, such as
BSF, are performed on the TRISC register
while the SS pin is high, this will cause the
TRISC<5> bit to be set, thus disabling the
SDO output.
