Writing 1 to
requests LCD COM mode for COM[3:0] (all four simultaneously).
is read-only acknowledgement
from hardware; read of 1 acknowledges LCD COM mode is selected for COM[3:0]. Note that the request may be denied based on port function priority.
I/O management segment requests write to single segment pins and must be a redundancy of the
segment request(s). These are accessed with the
following registers:
•
–
Write 1 requests LCD SEG mode for the GPIO selected in the
n
position (applicable to P3.0 – P6.7 [32 segments total])
•
–
Write 1 requests LCD SEG mode for the GPIO selected in the
n
position (applicable to P7.0 – P7.7 [8 segments total])
The I/O management segment requests also have associated read-only acknowledgements from hardware:
•
.io_ack_n
–
Read of 1 acknowledges SEG mode selected for the GPIO selected in the
n
position (applicable to P3.0 – P6.7 [32 segments total])
•
.io_ack_n
–
Read of 1 acknowledges SEG mode selected for the GPIO selected in the
n
position (applicable to P7.0 – P7.7 [8 segments total])
The following table outlines the bit addresses for the LCD Port Configuration registers.
Writes to this register can only occur when OPM=0
.
