#131822 - waiting for a techie, I checked
Responding to: ???'s previous message
from the datasheet

Pg8
P1.0 to P1.7 16 to 21, 23, 24 8-bit quasi-bidirectional I/O port.
CT0I/INT2 16 Capture timer inputs for Timer T2,
or
External interrupt inputs.
CT1I/INT3 17
CT2I/INT4 18
CT3I/INT5 19
T2 20 T2 event input (rising edge triggered).
RT2 21 T2 timer reset input (rising edge triggered).
CTX0 23 CAN transmitter output 0 (note 2).
CTX1 24 CAN transmitter output 1 (note 2).

pg9
note 2 If the CAN-controller is in the reset state (e.g. after a power-up reset; CAN Control Register bit CR.0; see Section 13.5.3 Table 32), the CAN transmitter outputs are floating and the pins P1.6 and P1.7 can be used as open-drain port pins. After a power-up reset the port data is HIGH, leaving the pins P1.6 and P1.7 floating.
