• Manufacturer Part Number: upd70f3017ay
• Description: V850/sa1tm 32-/16-bit Single-chip Microcontroller
• Manufacturer: Renesas Electronics Corporation.

14.2.10 Port 11
settings can be controlled in 1-bit units. A pull-up resistor can be connected to bits 0 to 3 in 1-bit units (software pull-
up function).
Port 11
Port 11 includes P114, which is an input-only port, and P110 to P113, which comprise an I/O port for which I/O
P11 can be read/written in 1-bit or 8-bit units. However, bit 4 can only be read.
Remark
Port 11 includes the following alternate functions.

When port 11 (P11) is read, the pin levels at that time are read. Writing to P11
writes the values to that register. This does not affect the input pins.
