6.6 Type 2 Capture/Compare Registers

6.6.1 Type 2 Timer/Counter Capture/Compare Register (T2Cx)

egister Description:

ype 2 Timer/Counter Capture/Compare Register

egister Address:

T2C0:

Module 02h, Index 0Bh

T2C1: Module 02h, Index 0Fh

T2C2: Module 03h, Index 0Bh

Bits 15 to 0: Type 2 Timer/Counter Capture/Compare Register (T2Cx[15:0]).

This 16-bit register holds the compare value when

operating in compare mode and gets the capture value when operating in capture mode. When operating in 16-bit mode (T2MD = 0),

the full 16 bits are read/write accessible. If the dual 8-bit mode of operation is selected, the upper byte of T2Cx is inaccessible. T2Cx

reads while in the dual 8-bit mode return 00h as the high byte and writes to the upper byte of T2Cx are blocked. A separate T2CHx

Note: For convenience, the lower byte of T2Cx (T2Cx[7:0]) is referred to as T2CLx. Unlike T2CHx, there is no separate T2CLx register

and the low byte is always accessed through T2Cx.
