(1) In the V850ES/JG3-H and V850ES/JH3-H, the general-purpose port functions share pins with several peripheral

function I/O pins. Switch between the general-purpose port (port mode) and the peripheral function I/O pin
(alternate-function mode) by setting the PMCn register. Note the following cautions with regards to this register
setting sequence.
(a) Cautions on switching from port mode to alternate-function mode
Cautions on setting port pins
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 that unexpected operations may occur at that moment or depending on
the change of the pin states in accordance with the setting of the PFn, PFCn, and PFCEn registers.
A concrete example is shown in [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 as
[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 the

follows.
The SCL01 pin is used alternately as the P41/SOF0 pin. Select the valid pin function using the
PMC4, PFC4, and PF4 registers.
