19.4.1
These blocks filter out glitches on signals coming from the I
to one clock cycle is rejected. (See the description of the clock control register for details of
internal clock). This is specified for the faster I
slower I
These blocks also perform resynchronization of bus signals to the internal clock.
19.4.2
The clock generator has two functions. Firstly, it generates the SCL I
of the master or slave interface. Secondly, it controls the internal clock rate, used by filtering
blocks and the master and slave interfaces. This operates as a clock-enable signal to the registers
in the filter, master, and slave interfaces.
19.4.3
Master and slave interfaces run independently and in parallel. The master interface controls the
transmission of address and data on the I
part in transmissions if its programmed address is seen on the bus. Both interfaces communicate
with the control register and the status registers independently. Only one interrupt line comes from
the I
19.4.4
To make software interface to the I
statuses are interlocked in the master and slave interface operations. The status bits involved are
described below.
(1) MDR and SDR (Single Buffer Mode)
MDR and SDR are set to 1 when data is received. Clear these bits to 0 after reading the receive
data register. If data is received while MDR and SDR are 1, hardware recognizes that unread data
remains in the receive data register, automatically holds SCL at low level and suspends data
transfer. In this case, clearing these bits to 0 after reading the receive data will resume transfer.
When receiving data consecutively, be sure to clear MDR and SDR to 0 after reading the receive
data register.
