Additionally, registers are provided for 2 values with configurable display properties.
The display for these 2 values can be configured as detailed below.
A text, up to 4 characters long, can be displayed in the upper screen area. This custom text is
configured with two registers, each character encoded as 8-bits. Only A-Z uppercase chars,
numbers, minus sign / and space are supported.
The ‘Attributes’ register is bitwise interpreted as follows:
Bit0: scale

1: scale = 0.1
Bits 1&2: basic symbols
00: none
01: Indoor icon
