The Timer0 interface consists of six MMRs, shown in Table 108.
Table 108. Timer0 Interface MMRs
Name
Description
T0LD
A 16-bit register that holds the 16-bit value loaded
into the counter. Available only in 16-bit mode.
T0CAP
A 16-bit register that holds the 16-bit value captured
by an enabled IRQ event. Available only in 16-bit mode.
T0VAL0/
T0VAL1
TOVAL0 is a 16 bit register that holds the 16 least
significant bits (LSBs).
T0VAL1 is a 32-bit register that holds the 32 most
significant bits (MSBs).
T0VAL0 and T0VAL1 are read only. In 16-bit mode, 16-
bit T0VAL0 is used. In 48-bit mode, both 16-bit T0VAL0
and 32-bit T0VAL1 are used.
T0ICLR
An 8-bit register. Writing any value to this register
clears the interrupt. Available only in 16-bit mode.
T0CON
The configuration MMR (see Table 109).

T0VAL0 and T0VAL1 are 16-bit and 32-bit registers that hold
the 16 least significant bits and 32 most significant bits,
respectively. T0VAL0 and T0VAL1 are read-only. In 16-bit
mode, 16-bit T0VAL0 is used. In 48-bit mode, both 16-bit
T0VAL0 and 32-bit T0VAL1 are used.
