Page 5: Product Description
1 Product Description The TCP460 is a standard 3U 32 bit CompactPCI module and offers 16 channels of high performance serial interface. Five different standard modules are available: The TCP460-10 provides 16 RS232 interfaces. The TCP460-11 provides 16 RS422 interfaces. The TCP460-12 provides 8 RS232 and 8 RS422 interfaces. -

Page 8: Cpci/Pci Interface
3 cPCI/PCI Interface The TCP460 uses two Exar XR17D158 octal PCI-UARTs to provide and control the 16 serial channels. A transparent 32 bit / 66 MHz PCI-to-PCI Bridge provides access to the two octal PCI- UARTs. The PCI-to-PCI Bridge allows 32 bit accesses on the local PCI bus and permits the high data throughput necessary for the high performance serial interfaces. -

The Device Configuration Registers control general operating conditions and monitor the status of various functions. This includes a 16 bit general purpose counter, multipurpose input/outputs (not supported by the TCP460), sleep mode, soft-reset and device identification, and revision. They are embedded inside the UART 0 Register Set. -

Page 20: Programming Hints
6 Programming Hints 6.1 UART Baud Rate Programming Each of the 16 UART channels of the TCP460 provides a programmable Baud Rate Generator. The clock of the XR17D158 UART can be divided by any divisor from 1 to 2 – 1. The divisor can be programmed by the UART channel DLM (Divisor MSB) and DLL (Divisor LSB) registers. - Page 21 3. Set UART channel EFR register bit 4 to '0' (latch modified MCR register setting). Note that the maximum baud rate for RS232 channel is 921.6 kps. Thus the minimum divisor value for RS232 channels is 0x0003 with MCR[7] = 0. TCP460 User Manual Issue 1.1 Page 21 of 32...
