TB0RG0H/L and the register buffer 10 both have the same memory addresses
(1188H and 1189H) allocated to them. If <TB0RDE> = "0", the value is written to both
the timer register and the register buffer 10. If <TB0RDE> = "1", the value is written
to the register buffer 10 only.
The addresses of the timer registers are as follows:
TMRB0
TB0RG0H/L
Upper 8 bits
(TB0RG0H)
1189H
TMRB1
TB1RG0 H/L
Upper 8 bits
(TB1RG0H)
1199H
The timer registers are write-only registers and thus cannot be read.
Lower 8 bits
Upper 8 bits
(TB0RG0L) (TB0RG1H)
1188H 118BH
Lower 8 bits Upper 8 bits
(TB1RG0L) (TB1RG1H)
1198H 119BH
92CZ26A-299

TB0RG1 H/L
Lower 8 bits
(TB0RG1L)

TB1RG1 H/L
