# NAME

`tcpcib` — Intel Atom E600 series LPC bridge, timecounter and watchdog timer

# SYNOPSIS

`tcpcib* at pci?`
`isa* at tcpcib?`

# DESCRIPTION

The `tcpcib` driver provides support for the Intel Atom E600 series LPC bridge and implements a 64-bit 14.3 MHz timecounter using the HPET timer.

The `tcpcib` driver also provides the standard watchdog(4) interface to the watchdog timer and may be used with watchdogd(8). The watchdog timer can be configured via sysctl(8).

Once the watchdog timer resets the CPU, the driver reports it on the next boot displaying the “reboot on timeout” message in the dmesg(8).

The maximum timeout value supported by the watchdog timer is 600 seconds.

# BUGS

Apart from the core pcib(4) functionality, timecounter and the watchdog(4) interface, the driver doesn't support any other aspects of the hardware.
