BAUD RATE PRESCALER REGISTER (BRPR)
Address: 005Dh - Read/Write in Stand-by mode
Reset Value: 00h
RJW[1:0]
determine the maximum number of time
quanta by which a bit period may be shortened or
lengthened to achieve resynchronization.
t
RJW
= t
CAN
* (RJW + 1)
BRP[5:0]
determine the CAN system clock cycle
time or time quanta which is used to build up the in-
dividual bit timing.
t
CAN
= t
CPU
* (BRP + 1)
Where t
CPU
= time period of the CPU clock.
The resulting baud rate can be computed by the for-
mula:
Note: Writing to this register is allowed only in
Stand-by mode to prevent any accidental CAN
protocol violation through programming errors.
BIT TIMING REGISTER (BTR)
Address: 005Eh - Read/Write in Stand-by mode
Reset Value: 23h
BS2[2:0]
determine the length of Bit Segment 2.
t
BS2
= t
CAN
* (BS2 + 1)
BS1[3:0]
determine the length of Bit Segment 1.
t
BS1
= t
CAN
* (BS1 + 1)
Note: Writing to this register is allowed only in
Stand-by mode to prevent any accidental CAN
protocol violation through programming errors.
PAGE SELECTION REGISTER (PSR)
Address: 005Fh - Read/Write
Reset Value: 00h
PAGE[2:0]
determine which buffer or filter page is
mapped at addresses 0060h to 006Fh.
