ZILOG INTELLIGENT PERIPHERAL
Z85230 ESCC™ CONTROL REGISTERS
See Figures 52 and 53 for the ESCC Control registers. For
additional information, refer to the ESCC Product
Specification /Technical Manual.
The Z80182/Z8L182 has two ESCC channels. They can be
accessed in any page of I/O space since only the lowest
eight address lines are decoded for access. Their Z180™
MPU Address locations are shown in Table 11.
When the 16550 MIMIC interface is enabled, ESCC channel
B is disconnected from the output pins. The channel B
/TRxCB clock is connected to the Transmit and Receive
timers of the 16550 MIMIC interface. It is recommended
that /TRxCB be programmed as an output with proper
baud rate values to timeout the transmitter and receiver
of the 16550 MIMIC interface.
