2. Driver
2.1. Overview
This library provides a set of peripheral function control programs (peripheral drivers) for Renesas
microcontrollers and allows the peripheral driver to be built into a user program.
2.2. Control Functions summary
This library has the following control functions available as peripheral drivers.
(1) Clock Generation Circuit
These driver functions are used to configure the multiple internal clock signals.
(2) Interrupt
These driver functions are used for configuring the external interrupt pins, handling fixed interrupts and
controlling the interrupt priority.
(3) I/O Port
These driver functions are used to configure the I/O pins and provide data read, write, compare and
modify operations.
(4) Port Function
These driver functions are used for configuring the I/O pin optional functions.
(5) MCU Operation
These driver functions are used for configuring the MCU operation.
(6) Low Power Consumption
These driver functions are used for selecting lower power consumption.
(7) Voltage Detection Circuit
These driver functions are used for configuring the low-voltage detection response.
(8) Bus Controller
These driver functions are used for configuring the external address bus, data bus and chip select pins
and handling any bus errors.
(9) DMA Controller
These driver functions are used for configuring and controlling the transfer of data within the address
space.
(10) External DMA Controller
These driver functions are used for configuring and controlling the transfer of data within the address
space.
(11) Data Transfer Controller
These driver functions are used for configuring and controlling the transfer of data triggered by
peripheral interrupts.
(12) Multi-Function Timer Pulse Unit
These driver functions are used for configuring and controlling the multi-function timers.
(13) Port Output Enable
These driver functions are used for additional configuring and controlling of the timer outputs.
(14) Programmable Pulse Generator
These driver functions are used for configuring and controlling the pulse generator outputs.
(15) 8-bit Timer
