7.3.18 Data Counter Register (I2C_CNT)

CAUTION

During an active transfer phase (between STT has been set to 1 and
receiving of ARDY), no modification must be done in this register. Changing
it may result in an unpredictable behavior.

This read/write register is used to control the numbers of bytes in the I2C data payload.

DCOUNT

0-FFFFh

Data count. I2C Master Mode only (receive or transmit; F/S).

This 16-bit countdown counter decrements by 1 for every byte received or sent through the I2C
interface. A write initializes DCOUNT to a saved initial value. A read returns the number of bytes that
are yet to be received or sent. A read into DCOUNT returns the initial value only before a start
condition and after a stop condition.

When DCOUNT reaches 0, the core generates a stop condition if a stop condition was specified
(I2C_CON.STP = 1) and the ARDY status flag is set to 1 in the I2C_IRQSTATUS_RAW register.

Note that DCOUNT must not be reconfigured after I2C_CON.STT was enabled and before ARDY is
received.

Note1: In case of I2C mode of operation, if I2C_CON.STP = 0, then the I2C asserts SCL = 0 when
DCOUNT reaches 0. The CPU can then reprogram DCOUNT to a new value and resume sending or
receiving data with a new start condition (restart). This process repeats until the CPU sets to 1 the
I2C_CON.STP bit.

The ARDY flag is set each time DCOUNT reaches 0 and DCOUNT is reloaded to its initial value.

0

Data counter = 65536 bytes (216)

1

Data counter = 1 bytes

-

-

FFFFh

Data counter = 65535 bytes (216 - 1)

Values after reset are low (all 16 bits).

Note2: Since for DCOUNT = 0, the transfer length is 65536, the module does not allow the possibility
to initiate zero data bytes transfers.
