The XFRLEN1 and XFRLEN2 bit fields (see Table 34-56) determine how many serial words are in phase 1 and in phase 2, respectively, of the transmit data frame.
Register | Bit | Name | Function | Type | Reset Value | |
---|---|---|---|---|---|---|
XCR1 | 14-8 | XFRLEN1 | Transmit frame length 1 | R/W | 000 0000 | |
(XFRLEN1 + 1) is the number of serial words in phase 1 of the transmit frame. | ||||||
XFRLEN1 = 000 0000 | 1 word in phase 1 | |||||
XFRLEN1 = 000 0001 | 2 words in phase 1 | |||||
| | | | |||||
| | | | |||||
XFRLEN1 = 111 1111 | 128 words in phase 1 | |||||
XCR2 | 14-8 | XFRLEN2 | Transmit frame length 2 | R/W | 000 0000 | |
If a dual-phase frame is selected, (XFRLEN2 + 1) is the number of serial words in phase 2 of the transmit frame. | ||||||
XFRLEN2 = 000 0000 | 1 word in phase 2 | |||||
XFRLEN2 = 000 0001 | 2 words in phase 2 | |||||
