7.2.4 Type 2 Capture/Compare Registers
The MAXQ7665/MAXQ7666 timer/counter module registers T2Cx (timer capture/compare) and T2CHx (timer capture/compare high),
where x = 0, 1, and 2, are described here.
7.2.4.1 Type 2 Timer/Counter Capture/Compare Register (T2Cx)
Register Description: Type 2 Timer/Counter Capture/Compare Register
Register Name: T2Cx (x = 0, 1, 2)
Register 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 to T2Cx.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 register is provided to facilitate high-byte access.
Note: For convenience, the lower byte of T2Cx (T2Cx.7–T2Cx.0) is referred to as T2CLx. Unlike T2CHx, there is no separate T2CLx
register and the low byte is always accessed through T2Cx.
