Other Features for Z85C30 Only
Some of the features listed below are available by default. Some of them (features with )
are disabled on default to maintain compatibility with the existing Serial Communications
Controller (SCC) design, and “program to enable through WR7”:

New programmable WR7 (Write register 7 prime) to enable new features
Improvements to support SDLC mode of synchronous communication:
– Improve functionality to ease sending back-to-back frames
– Automatic SDLC opening Flag transmission
– Automatic Tx Underrun/EOM Latch reset in SDLC mode
– Automatic RTS deactivation
– TxD pin forced High in SDLC NRZI mode after closing flag
– Complete CRC reception
– Improved response to Abort sequence in status FIFO
– Automatic Tx CRC generator preset/reset
– Extended Read for Write registers
– Write data set-up timing improvement
• Improved AC timing:
– 3 to 3.6 PCLK access recovery time
– Programmable DTR/REQ timing
– Write data to falling edge of WR setup time requirement is now eliminated
– Reduced INT timing
• Other features include:
– Extended Read function to read back the written value to the Write registers
– Latching RRO during read
– RRO, bit D7 and RR10, bit D6 now has reset default value

General Description
The Z80C30/Z85C30 Serial Communications Controller (SCC), is a pin and software
compatible CMOS member of the SCC family introduced by Zilog in 1981. It is a dualchannel,
multiprotocol data communications peripheral that easily interfaces with CPU’s
with either multiplexed or nonmultiplexed address/data buses.
The advanced CMOS process offers lower power consumption, higher performance, and
superior noise immunity. The programming flexibility of the internal registers allow the
SCC to be configured to various serial communications applications.
The many on-chip features such as Baud Rate Generators (BRG), Digital Phase Locked
Loops (DPLL), and crystal oscillators reduce the need for an external logic.
Additional features include a 10 x 19-bit status FIFO and 14-bit byte counter to support
high speed SDLC transfers using DMA controllers.
The SCC handles asynchronous formats, synchronous byte-oriented protocols such as
IBM Bisync, and synchronous bit-oriented protocols such as HDLC and IBM SDLC. This
device supports virtually any serial data transfer application (for example, cassette,
diskette, tape drives, etc.).
The device generates and checks CRC codes in any synchronous mode and can be
programmed to check data integrity in various modes. The SCC also contains facilities for
modem controls in both channels. In applications where these controls are not required,
the modem controls can be used for general-purpose I/O. The daisy-chain interrupt hierarchy
is also supported.
Figure 1 displays a block diagram of the SCC.
