Z85230 ESCC
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.
