General System Integration of ESCC2
Figure 5 gives a general overview of system integration of ESCC2.
The ESCC2’s bus interface consists of an 8/16-bit bidirectional data bus (D0 … D15),
seven Address Line inputs (A0 … A6), three control inputs (RD/DS, WR/R/W, CS), four
signals for interrupt support (INT, INTA, IE0, IE1) and a 4-channel DMA interface (DRTA,
DRRA, DACKA, DRTB, DRRB, DACKB). Mode input pins (strapping options) allow the
bus interface to be configured for 8/16-bit bus width and for either Siemens/Intel or
Motorola environment.
Generally, there are two types of transfers occurring via the system bus:
– Command/Status transfers, which are always controlled by the CPU. The CPU sets
– Data Transfers, which are effectively performed by DMA without CPU interaction
Semiconductor Group
the operation mode (initialization), controls function sequences and gets status
information by writing or reading the ESCC2’s registers (via CS, WR or RD, and
register address via A0 … A6).
using the ESCC2’s DMA interface (DMA mode). Optionally, interrupt controlled data
transfer can be done by the CPU (interrupt mode).
