NAME

csx_Put8, csx_Put16, csx_Put32, csx_Put64 - write to device register

SYNOPSIS

#include <sys/pccard.h>
void csx_Put8(acc_handle_t handle, uint32_t offset, uint8_t value);

void csx_Put16(acc_handle_t handle, uint32_t offset, uint16_t value);

void csx_Put32(acc_handle_t handle, uint32_t offset, uint32_t value);

void csx_Put64(acc_handle_t handle, uint32_t offset, uint64_t value);

INTERFACE LEVEL

illumos DDI Specific (illumos DDI)

PARAMETERS

handle

The access handle returned from csx_RequestIO(9F), csx_RequestWindow(9F), or csx_DupHandle(9F).

offset

The offset in bytes from the base of the mapped resource.

value

The data to be written to the device.

DESCRIPTION

These functions generate a write of various sizes to the mapped memory or device register.

The csx_Put8(), csx_Put16(), csx_Put32(), and csx_Put64() functions write 8 bits, 16 bits, 32 bits, and 64 bits of data, respectively, to the device address represented by the handle, handle, at an offset in bytes represented by the offset, offset.

Data that consists of more than one byte will automatically be translated to maintain a consistent view between the host and the device based on the encoded information in the data access handle. The translation may involve byte swapping if the host and the device have incompatible endian characteristics.

CONTEXT

These functions may be called from user, kernel, or interrupt context.
