Chapter 15 Inter-Integrated Circuit (IICV3) Block Description
transfer. In the broadcast, slaves always act as receivers. In general call, IAAS is also used to indicate the
address match.
In order to distinguish whether the address match is the normal address match or the general call address
match, IBDR should be read after the address byte has been received. If the data is $00, the match is
general call address match. The meaning of the general call address is always specified in the first data byte
and must be dealt with by S/W, the IIC hardware does not decode and process the first data byte.
When one byte transfer is done, the received data can be read from IBDR. The user can control the
procedure by enabling or disabling GCEN.
15.4.2
This is the basic mode of operation.
15.4.3
IIC operation in wait mode can be configured. Depending on the state of internal bits, the IIC can operate
normally when the CPU is in wait mode or the IIC clock generation can be turned off and the IIC module
enters a power conservation state during wait mode. In the later case, any transmission or reception in
progress stops at wait mode entry.
15.4.4
The IIC is inactive in stop mode for reduced power consumption. The STOP instruction does not affect IIC
register states.
15.5
The reset state of each individual bit is listed in
which details the registers and their bit-fields.
15.6
IICV3 uses only one interrupt vector.
Internally there are three types of interrupts in IIC. The interrupt service routine can determine the interrupt
type by reading the status register.
IIC Interrupt can be generated on
