(1) In the V850ES/JG3-L, general-purpose port pins are shared with several peripheral I/O functions. To switch
Cautions
between using a pin as a general-purpose port pin (port mode) and as a peripheral function I/O pin (alternate-
function mode), use the PMCn register. Note the following when setting this register.
(a) Cautions when switching from port mode to alternate-function mode
Cautions on setting port pins
Switch from the port mode to the 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
Note that if the PMCn register is set first, an unexpected operation may occur at the moment the register is
set or when the pin states change in accordance with the setting of the PFn, PFCn, and PFCEn registers.
A specific example is shown below.
Notes 1. N-ch open-drain output pin only.
Caution Regardless of the port mode/alternate-function mode setting, the Pn register is read and

2. Only when the external interrupt function is selected.
• Pn register read: The port output latch value is read (when PMn.PMnm bit = 0), or the
• Pn register write: The port output latch is written

The SCL01 pin is used alternately as the P41/SOB0 pin. Select the desired pin function by
using the PMC4, PFC4, and PF4 registers.
