Bits 11:10 – HDRDLY[1:0]: LIN Master Header Delay

LIN Master Header Delay

These bits define the delay between break and sync transmission in addition to the delay between the sync and identifier (ID) fields when in LIN master mode (CTRLA.FORM=0x2).

This field is only valid when using the LIN header command (CTRLB.LINCMD=0x2).

ValueDescription
0x0

Delay between break and sync transmission is 1 bit time.

Delay between sync and ID transmission is 1 bit time.

0x1

Delay between break and sync transmission is 4 bit time.

Delay between sync and ID transmission is 4 bit time.

0x2

Delay between break and sync transmission is 8 bit time.

Delay between sync and ID transmission is 4 bit time.

0x3

Delay between break and sync transmission is 14 bit time.

Delay between sync and ID transmission is 4 bit time.

Bits 9:8 – BRKLEN[1:0]: LIN Master Break Length

LIN Master Break Length

These bits define the length of the break field transmitted when in LIN master mode (CTRLA.FORM=0x2).
ValueDescription
0x0 Break field transmission is 13 bit times
0x1 Break field transmission is 17 bit times
0x2 Break field transmission is 21 bit times
0x3 Break field transmission is 26 bit times

Bits 2:0 – GTIME[2:0]: Guard Time

Guard Time

These bits define the guard time when using RS485 mode (CTRLA.TXPO=0x3).

For RS485 mode, the guard time is programmable from 0-7 bit times and defines the time that the transmit enable pin (TE) remains high after the last stop bit is transmitted and there is no remaining data to be transmitted.
