3:2 GPIO2[1:0] General Purpose I/O 2.
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 GPIO2 when the STC 0Ah[14] bit is
set. Setting RDSIEN = 1 will generate a 5 ms low pulse on GPIO2 when the RDSR
0Ah[15] bit is set.
1:0 GPIO1[1:0] General Purpose I/O 1.
00 = High impedance (default).
01 = Reserved.
10 = Low.
11 = High.
