PIN[3:0] Access Sequential:
The top marking of W86L387D
Write parallel port control to enable the
related PIEN input.
Write interrupt register to enable the
PIN interrupt.
Read parallel port data register,
PIN[3:0] = low
Wait for interrupt input.
Read interrupt status register and
check is PIN interrupt.
Read parallel port data register, PIN =
high.
Read parallel port data register, PIN =
low.
Read interrupt status register, PIN
interrupt = high.
Read status register, INT bit = low.
Wait for TPC command.
