RL78/D1A CHAPTER 13 ASYNCHRONOUS SERIAL INTERFACE LIN-UART (UARTF)
(19) Port mode registers 1, 7, 13 (PM1, PM7, PM13)
The PM1, PM7 and PM13 registers are used to set ports 1, 7, and 13 to input or output in 1-bit units.
The PM1, PM7 and PM13 registers can be set by using a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets these registers to FFH (PM13 is set to FEH).
Caution The shaded pins are provided at two ports. Select either port by using the corresponding
register.
Remarks 1. The pins mounted depend on the product. See 1.4 Ordering Information and 2.1 Pin Function
List.
2. See CHAPTER 4 PORT FUNCTIONS for port settings.
