My apology. The current code is _OFF, although that hasn't made
a difference. That aside, after a POR you can remap once

Alan and Martin asked about the configs. I can't see what else is
needed that affects the pins

DELAYPT5 is a 0.5s delay

I've included a test in the loop, to no effect

do_spi:    btsc    SPI1STAT,#SPITBF
           bra     do_spi          ;buffer not empty

The SPI loop is executing at 1Hz, as indicated by the flashing '*', just as
it was

Oddly, I've skipped over the remapping and left the default reset
assignments and expected to see a 1Hz wave on RP10 with this
loop

do_pin:    bset    LATB,#RB10
           call    delaypt5
           bclr    LATB,#RB10
           call    delaypt5
           bra     do_pin

In the disassembly is

BCLR.B 0x02CD,#2 and BSET.B 0x02CD,#2, 0x02CD being the
upper byte of LATB, so straight after power-up that should mean
activity on RP10. There's something missing in the set-up which is
preventing instructions being seen at the pin

LATA 0,1,4 and LATB <3:0> seem to be fine though, they're what's
driving the LCD, no problem
