5. MUTUAL EXCLUSIVE FUNCTIONS
The IPC@CHIP family microcontroller provides a lot of different functions by several multi-function
pins. Choosing one function will result in disabling other functions. The following table shows, which
functions are mutual exclusive.
Pin Name Function Exclusion
A0 nonmultiplexed address A0 PIO4, PCS1#, TMRIN0
A[1..2] nonmultiplexed address
A[1..2]
PIO[2..3], PCS[5..6], Timer 1
ALE Address / Data bus PCS0#
CTS0 hardware flow control Serial
Port 0
PIO9
CTS1 hardware flow control Serial
Port 1
PIO6, PCS2#, INT2, INTA#, PWD
DRQ0 DMA Request 0 PIO1, INT5, I

C-Bus by default PIO[0..1], DMA, INT[5..6]
By default pin-assignment of the I

C functions is in
conflict with these pin functions, but the user is free to
assign the I
2
C functions to any other PIO pin,
disabling the other functions of the pin chosen.
