Bit 7
RFCENB: RFC function control bit.
0 = Disable RFC function.
1 = Enable RFC function.
Bit 5
Bit 4
RFCM.5 must be set as “0” by program.
RFCM.4 must be set as “1” by program.
Bit 3
RFCOUT: RFC output control bit.
0 = Disable RFC output, P1.6 is general purpose I/O.
1 = Enable RFC output, P1.6 is RFCOUT pin.
Bit[2:1]
RFCH[2:1]: RFC input channels select bit.
000 = Select RFC0 channel. Disable P1.0 GPIO function. P1.1, P1.2, P1.3, P1.4 are GPIO mode.
001 = Select RFC1 channel. Disable P1.1 GPIO function. P1.0, P1.2, P1.3, P1.4 are GPIO mode.
010 = Select RFC2 channel. Disable P1.2 GPIO function. P1.0, P1.1, P1.3, P1.4 are GPIO mode.
011 = Select RFC3 channel. Disable P1.3 GPIO function. P1.0, P1.1, P1.2, P1.4 are GPIO mode.
100 = Select RFC4 channel. Disable P1.4 GPIO function. P1.0, P1.1, P1.2, P1.3 are GPIO mode.
101~111 = Reserved. P1.0, P1.1, P1.2, P1.3, P1.4 are GPIO mode.

Note:
1. Before RFC enable, P1.0~P1.4 must be set as input mode without pull-up resistor first by
program.
2. RFCM.4 must be set as “1” by program through MOV/B0MOV instruction because the bit is write
only type.
3. RFCM.5 must be set as “0” by program through MOV/B0MOV instruction because the bit is write
only type.
4. We strongly recommend controlling RFCM register through MOV/B0MOV instructions.
