P4CON0 and P4CON1 are special function registers (SFRs) used to select the output state of the port 4 pin. The
output state is different between input mode and output mode. Input or output is selected by using the P4DIR
register.
Description of Bits
•
P47-40C0
(bits 7 to 0)
, P47-40C1
(bits 15 to 8)
The P47-40C0 and P47-40C1 bits are used to select high-impedance output, P-channel open drain output,
N-channel open drain output, or CMOS output in output mode and to select high-impedance input, input
with a pull-down resistor, or input with a pull-up resistor in input mode.
To perform the direct LED drive, select N-channel open drain output mode.
Setting of P40 pin
When output mode is selected
(P40DIR bit = “0”)
When input mode is selected
(P40DIR bit = “1”)
