If BUSIE is cleared PA0 and PA1 operate as normal I/O pins. IF BUSIE is set the input schmitt trigger of
PA1 is connected with data input of the CAN controller. The data output of the CAN controller is con-
nected with the output driver of PA0 as well. For this mode of operation PA0 has to be programmed as
output, PA1 as input. In this operation mode port A data register bit 0 is connected with line interface
open drain output buffer. Therefore BUSOUT is directly controlled by port A data register bit 0.
Pin PA2 may also be used as external input for TIMER1. For this purpose PA2 has to be programmed
as input (with or without pull up / interrupt) and bit TEST of oscillator control register OSCR has to be
cleared.
With BUSIE = 1 bit PA1 has to be configured as Input, bit PA0 as output.
