Table 8-19 Timer 0 Data Byte 0 (LSB) (0x654)
Bit
R/W
Description
Default
7:0
R/W
Read value depends on value of CSR1(3).
If '0' - Contains Bits 7-0 of the Timer current counter
value
If '1' - Contains Bits 7-0 of the Timer load value
Reading this register latches the upper bits of the count
value to prevent rollover. Write always updates Timer
load value.

If '0' - Contains Bits 15-8 of the Timer current counter
value
If '1' - Contains Bits 15-8 of the Timer load value
Reading this register latches the upper bits of the count
value to prevent rollover. Write always updates Timer
load value.
