8-Bit Timer/Counter (continued)
Two counter inputs (load, enable) control the counter operation. The load input controls load operations. A
write-access to the counter results in loading the content of the preload-register into the counter. The software
writes or reads the preload-register with all instructions. The preload-register acts as a buffer and can be written
immediately after the load of the counter is completed. The enable input enables the count operation. When
the enable signal is set to high, the counter will count up each time a positive clock edge is applied to the clock
input of the counter.
Serial protocols, like UART protocol, need start-bit edge-detection to determine, at the receiver, the start of a
data transmission. When this function is activated, the counter starts counting after start-bit condition is
detected. The first signal level is sampled into the RXD input data-latch after completing the first timing interval,
which is programmed into the counter. Two latches used for input and output data (RXD_FF and TXD_FF) are
clocked by the counter after the programmed timing interval has elapsed.
UART
The serial communication is realized by using software and the 8-bit timer/counter hardware. The hardware
supports the output of the serial data stream, bit-by-bit, with the timing determined by the counter. The
software/hardware interface connects the mixed signal controller to external devices, systems, or networks.
