Description

Microchip XEC basic timer properties

Properties

Properties not inherited from the base binding file.

Name

Type

Details

clock-frequency

int

 
Basic timer input clock is 48 MHz.

This property is required.

Constant value: 48000000

max-value

int

 
Counter maximum value. The SoC contains multiple instances
of the basic timer. Some are 16-bit, others 32-bit.

This property is required.

prescaler

int

 
Basic timer implements a 16-bit clock prescale value.
Count frequency is clock-frequency divided by (prescaler + 1).

This property is required.

girqs

array

 
Many DEC/MEC periperals interrupt signals are direct capable. The signals are
connected to bits in a GIRQ. Each GIRQ is composed of 5 32-bit registers:
status(latched or r/w1-c), set-enable, clr-enable, and result (read-only).
The read-only result register bits are the bitwise AND of status and enable.
Direct mode routes the individual result register bits to NVIC inputs. If
direct mode is disable by setting direct mode bit to 0 in the EC subsystem
interrupt control register then the result register outputs are OR'd together
and the OR'd result is connected to an NVIC input based on GIRQ number.
To enable an interrupt a driver must know:
a. NVIC input number and priority from the interrupts property
b. GIRQ number and bit position from the girqs property
The number of entries in interrupts and girqs should be the same in a DT node.

This property is required.
