Bit
Name
Function
3:2 GPO[1:0] General Purpose I/O.
00 = High impedance (default).
01 = STC/RDS interrupt. A logic high will be output unless an interrupt occurs as
described below.
10 = Low.
11 = High.
Setting STCIEN = 1 will generate a 5 ms low pulse on GPO when the STC 0Ah[14] bit is
set. Setting RDSIEN = 1 will generate a 5 ms low pulse on GPO when the RDSR 0Ah[15]
bit is set.
1:0 Reserved Always write to 10.
