Register 0xF5: RASE Receive K1
| Bit | Type | Function | Default | 
| Bit 7 | R | K1[7] | X | 
| Bit 6 | R | K1[6] | X | 
| Bit 5 | R | K1[5] | X | 
| Bit 4 | R | K1[4] | X | 
| Bit 3 | R | K1[3] | X | 
| Bit 2 | R | K1[2] | X | 
| Bit 1 | R | K1[1] | X | 
| Bit 0 | R | K1[0] | X | 
K1[7:0]:
The K1[7:0] bits contain the current K1 code value. The contents of this register are updated when a new K1 code value (different from the current K1 code value) is received for three consecutive frames. An interrupt may be generated when a new code value is received (using the COAPSE bit in the RASE Interrupt Enable Register). K1[7] is the most significant bit corresponding to bit 1, the first bit received. K1[0] is the least significant bit, corresponding to bit 8, the last bit received.
