EM6617-1
EM Microelectronic-Marin SA , 3/99 Rev. B/258

The EM6617-1 has one globally configurable Input / Output port which is 4 bit wide (only two bits are available
for 24 pin packages). Input or output mode can be set by writing the bit
PCIOCntl
in
RegPCCntl
register.
“0“ = input mode (default), “1“ = output mode. The
RegPCData
register is used to write output data on port C.
Input data is read directly on the input terminal and put onto the internal data bus. It is not stored in the
RegPCData
register. The port C terminal status can be read on address
RegPCData
even in output mode. Be
aware that the data read on port C is not necessary of the same value as the data stored on
RegPCData
register.
At any reset, the
RegPCCntl
register is cleared, thus setting the port in input mode. During SLEEP mode,
PC[3:0] are in high impedance state.
The port C is globally configurable to act as CMOS or Nch. open drain port , selectable in
OPTPCandStr
register (
NchOpDPC
bit).
7.6.1 Pull-up or Pull-down
On each terminal of PC[3:0] an internal input pull-up (metal mask MPCPU[n]) or pull-down (metal mask
MPCPD[n]) resistor can be connected per metal mask option. Per default the two resistors are in place. In this
case one can chose per software to have either a pull-up, a pull-down or no resistor.
