1 _{Physical RAM in $000E can be accessed through D[X] register when the content of the index register X is $0E.}
2 _{If using the MCU untrimmed, $3FFA and $3FFB may be used by applications.}
The ICS factory-trimmed value will be stored in 0x3FFA and 0x3FFB (bit 0). The factory-trimmed bus
frequency is 10 MHz.
4.5 RAM
The device includes three static RAM sections. The locations from $0000 to $000D can be directly
accessed using the more efficient tiny addressing mode instructions and short addressing mode
instructions. Location $000E RAM can be accessed through D[X] register when register X is $0E or
through the paging window location $00CE when PAGESEL register is $00. The second section of RAM
starts from $0030 to $00BF and can be accessed using direct addressing mode instructions. The third
section of RAM starts from $0100 to $015F.
The RAM retains data when the MCU is in low-power wait and stop mode. RAM data is unaffected by
any reset if the supply voltage does not drop below the minimum value for RAM retention.
