• Bit 2:0 - ISC[2:0]: Input/Sense Configuration
These bits set the input and sense configuration on pin n according to
configuration decides how the pin can trigger port interrupts and events. When the input buffer is
not disabled, the schmitt triggered input is sampled (synchronized) and can be read in the IN
register.
Table 13-5.
Note:
• Bit 7:0 - MPCMASK[7:0]: Multi-pin Configuration Mask
The MPCMASK register enables several pins in a port to be configured at the same time. Writing
a one to bit n allows that pin to be part of the multi-pin configuration. When a pin configuration is
written to one of the PINnCTRL registers of the port, that value is written to all the PINnCTRL
registers of the pins matching the bit pattern in the MPCMASK register for that port. It is not nec-
essary to write to one of the registers that is set by the MPCMASK register. The MPCMASK
register is automatically cleared after any PINnCTRL registers is written.
