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. Table 11.
