17.4.13 Port E Input Pins Address

Name: PINE

Offset: 0x2C

Reset: N/A

Property: When addressing as I/O Register: address offset is 0x0C

When addressing I/O registers as data space using LD and ST instructions, the provided offset must be

used. When using the I/O specific commands IN and OUT, the offset is reduced by 0x20, resulting in an

I/O address offset within 0x00 - 0x3F.

The device is a complex microcontroller with more peripheral units than can be supported within the 64

locations reserved in Opcode for the IN and OUT instructions. For the extended I/O space from 0x60 in

SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be used.
