Is it possible to use ISP mode at boot if an RS-485 transceiver is on the ISP UART?  If so, how does one control the direction (TxEnable) so an autobaud response can be sent?

The LPC2xxx has a means to control this via the reset and ISP entry pins.  But the LPC15xx has two ISP entry pins and I find no mention of the ISP code being able to control RTS in the manual.
