EC-Only Registers

The registers listed in the EC-Only Register Summary table are for a single instance of the Basic Timer. The addresses

of each register listed in this table are defined as a relative offset to the “Base Address” of that instance, defined in the

Device Inventory chapter and will follow the instance naming as listed in TABLE 13-5: “CEC1712 Instance Naming

Convention”.

COUNTER

This is the value of the Timer counter. This is updated by Hardware

but may be set by Firmware. If it is set while the Hardware Timer is

operating, functionality can not be guaranteed. When read, it is

buffered so single byte reads will be able to catch the full 4 byte

- For 16 bit Basic Timer, bits 0 to 15 are r/w counter bits.

Bits 31 down to 16 are reserved. Reads of bits 31 down to

16 return 0 and writes have no effect.

- For 32 bit Basic Timer, bits 0 to 31 are r/w counter bits.
