PIC32MZ Embedded Connectivity with Floating Point Unit (EF) Family
21.0 INTER-INTEGRATED
CIRCUIT™ (I
2
C™)
The I
2
C module provides complete hardware support
for both Slave and Multi-Master modes of the I
2
C serial
communication standard.
Each I
2
C module has a 2-pin interface:
• SCLx pin is clock
• SDAx pin is data
Each I
2
C module offers the following key features:
•I
2
C interface supporting both master and slave
operation
•I
2
C Slave mode supports 7-bit and 10-bit addressing
•I
2
C Master mode supports 7-bit and 10-bit addressing
•I
2
C port allows bidirectional transfers between
master and slaves
• Serial clock synchronization for the I
2
C port can be
used as a handshake mechanism to suspend and
resume serial transfer (SCLREL control)
•I
2
C supports multi-master operation; detects bus
collision and arbitrates accordingly
• Provides support for address bit masking
• SMBus support
Figure 21-1 illustrates the I
2
C module block diagram.
