12.11 - XPort 9
The XPort9 is enabled by setting XPEN bit 2 of the SYSCON register and XPORT9EN bit 3 of the new
XPERCON register. On the XBUS interface, the register are not bit-addressable
This 16-bit port is used for general purpose I/O, the direction of each line can be configured via the corre-
sponding direction register XDP9. Each port line can be switched into push/pull or open drain mode via
the open drain control register XODP9.
All port lines can be individually (bit-wise) programmed. The “bit-addressable” feature is available via spe-
cific “Set” and “Clear” registers: XP9SET, XP9CLR, XDP9SET, XDP9CLR, XODP9SET, XODP9CLR.

Writing a ‘1’ will set the corresponding bit in XP9 register, Writing a ‘0’ has no effect.
Writing a ‘1’ will clear the corresponding bit in XP9 register, Writing a ‘0’ has no effect.
Port direction register XDP9 bit y
XDP9.y = 0: Port line XP9.y is an input (high-impedance)
XDP9.y = 1: Port lineX P9.y is an output
