XMODE
XADDR register is used for peripheral address generation and XDATA register is used for peripheral data access.
PXC
independent of the BSW1-0 bits.
8.1.28 Monitor Receive Channel 0
Used when XMODE=0 only.
Used when XMODE=0 only.
Used when XMODE=0 only.
Used when XMODE=0 only.
Used when XMODE=0 only.
This bit determines whether or not the PCM ports are cross-connected with the B channel ports. The setting of PXC is
0: Pin IO10's output driver is disabled.
1: Pin IO10's output driver is enabled.
0: Pin IO9-8's output drivers are disabled.
1: Pin IO9-8's output drivers are enabled.
0: Pin IO7-6's output drivers are disabled.
1: Pin IO7-6's output drivers are enabled.
0 : Pin IO5-4's output drivers are disabled.
1 : Pin IO5-4's output drivers are enabled.
0 : Pin IO3-2's output drivers are disabled.
1 : Pin IO3-2's output drivers are enabled.
0 : Pin IO1-0's output drivers are disabled.
1 : Pin IO1-0's output drivers are enabled.
0: Simple programmable IO. This is the default state. XADDR register and XDATA register are used for data access.
1: 8-bit multiplexed microprocessor bus. Pins IO7-0 are used as XAD7-0, IO8 as XALE, IO9 as XRDB and IO10 as XWRB.
