19.3.2
Master mode of operation is supported in firmware
using interrupt generation on the detection of the Start
and Stop conditions. The Stop (P) and Start (S) bits are
cleared from a Reset or when the SSP module is
disabled. The Stop (P) and Start (S) bits will toggle
based on the Start and Stop conditions. Control of the
I
is Idle and both the S and P bits are clear.
In Master mode, the SCL and SDA lines are manipu-
lated by clearing the corresponding TRISC<5:4> or
TRISD<3:2> bits. The output level is always low,
regardless of the value(s) in PORTC<5:4> or
PORTD<3:2>. So when transmitting data, a ‘1’ data bit
must have the TRISC<4> bit set (input) and a ‘0’ data
bit must have the TRISC<4> bit cleared (output). The
same scenario is true for the SCL line with the
TRISC<4> or TRISD<2> bit. Pull-up resistors must be
provided externally to the SCL and SDA pins for proper
operation of the I
The following events will cause the SSP Interrupt Flag
bit, SSPIF, to be set (SSP interrupt will occur if
enabled):
• Start condition
• Stop condition
• Data transfer byte transmitted/received
Master mode of operation can be done with either the
Slave mode Idle (SSPM<3:0> = 1011) or with the
Slave active. When both Master and Slave modes are
enabled, the software needs to differentiate the
source(s) of the interrupt.

19.3.3
In Multi-Master mode, the interrupt generation on the
detection of the Start and Stop conditions allows the
determination of when the bus is free. The Stop (P) and
Start (S) bits are cleared from a Reset or when the SSP
module is disabled. The Stop (P) and Start (S) bits will
toggle based on the Start and Stop conditions. Control
of the I
is set, or the bus is Idle and both the S and P bits clear.
When the bus is busy, enabling the SSP interrupt will
generate the interrupt when the Stop condition occurs.
In Multi-Master mode, the SDA line must be monitored
to see if the signal level is the expected output level.
This check only needs to be done when a high level is
output. If a high level is expected and a low level is
present, the device needs to release the SDA and SCL
lines (set TRISC<5:4> or TRISD<3:2>). There are two
stages where this arbitration can be lost, these are:
• Address Transfer
• Data Transfer
When the slave logic is enabled, the slave continues to
receive. If arbitration was lost during the address
transfer stage, communication to the device may be in
progress. If addressed, an ACK pulse will be gener-
ated. If arbitration was lost during the data transfer
stage, the device will need to retransfer the data at a
later time.
