(1) In the V850ES/JF3-L, the general-purpose port function and several peripheral function I/O pin share a pin. To
Cautions
switch between the general-purpose port (port mode) and the peripheral function I/O pin (alternate-function
mode), set by the PMCn register. In regards to this register setting sequence, note with caution the following.
(a) Cautions on switching from port mode to alternate-function mode
Cautions on setting port pins
To switch from the port mode to alternate-function mode in the following order.
<1> Set the PFn register
<2> Set the PFCn and PFCEn registers:
<3> Set the corresponding bit of the PMCn register to 1: Switch to alternate-function mode
<4> Set the INTRn and INTFn registers
If the PMCn register is set first, note with caution that, at that moment or depending on the change of the
pin states in accordance with the setting of the PFn, PFCn, and PFCEn registers, unexpected operations
may occur.
A concrete example is shown as Example below.
Notes 1. N-ch open-drain output pin only
Caution Regardless of the port mode/alternate-function mode, the Pn register is read and written
[Example] SCL01 pin setting example
2. Only when the external interrupt function is selected
• Pn register read: Read the port output latch value (when PMn.PMnm bit = 0), or read
• Pn register write: Write to the port output latch
as follows.
The SCL01 pin is used alternately with the P41/SOB0 pin. Select the valid pin functions with
the PMC4, PFC4, and PF4 registers.
