CLINT_BASE_ADDR

#define CLINT_BASE_ADDR   (0xe0000000UL)

Base address of the RISC-V ACLINT (CLINT)

Definition at line 29 of file cpu_conf.h.

NUM_PMP_ENTRIES

#define NUM_PMP_ENTRIES   (16)

Number of available PMP regions.

Definition at line 52 of file cpu_conf.h.

PLIC_CTRL_ADDR

#define PLIC_CTRL_ADDR   (0xf8000000UL)

Base address of the PLIC.

Definition at line 35 of file cpu_conf.h.

PLIC_NUM_INTERRUPTS

#define PLIC_NUM_INTERRUPTS   (31U)

Number of interrupt sources in the PLIC.

Definition at line 41 of file cpu_conf.h.

PLIC_NUM_PRIORITIES

#define PLIC_NUM_PRIORITIES   (7U)

Number of priority levels in the PLIC.

Definition at line 47 of file cpu_conf.h.

RTC_FREQ

#define RTC_FREQ   (20000000UL)

MTIME clock frequency of the ACLINT.

GRLIB ACLINT runs mtime at CLOCK_CORECLOCK / 2. Must match CONFIG_ZTIMER_USEC_BASE_FREQ in board.h.
