P56MD1-0 (bits 14, 6)
The P56MD1-0 bits are used to select the primary, secondary, tertiary, or quartic function of the P56 pin.
P56MD1 P56MD0 Description
0 0 General-purpose input/output mode, External interrupt mode (initial
value)
0 1 Low speed clock output mode(LSCLKO)
1 0 Synchronous serial port with FIFO clock input/output mode (SCKF0)
1 1 FTM output mode (TMOUTE)
•
P57MD1-0 (bits 15, 7)
The P57MD1-0 bits are used to select the primary, secondary, tertiary, or quartic function of the P57 pin.
P57MD1 P57MD0 Description
0 0 General-purpose input/output mode, External interrupt mode (initial
value)
0 1 High speed clock output mode (OUTCLK)
1 0 Synchronous serial port with FIFO chip select input/output mode
(SSF0)
1 1 FTM output mode (TMOUTF)
[Note]
When the pin is set to “Prohibited” and the output mode is selected (by the Port 5 control register), the Port
5 output pin state is fixed as follows regardless of the data of the port data register P5D:
When high-impedance output is selected: Output pin is high-impedance
When P-channel open drain output is selected: Output pin is high-impedance
When N-channel open drain output is selected: Output pin is fixed to “L”
When CMOS output is selected: Output pin is fixed to “L”
