Research direction
Review the writing section of the Rust Embedded Book and compare its description of the PAC write() closure with the linked tm4c123x pwm0/ctl::W documentation. Clarify the access semantics so the text matches the provided API documentation. Done when the section accurately explains what W permits and no longer contradicts the link.
Written by the indexing model from the issue text.
Description
The section on writing to memory-mapped registers using a PAC says that the argument of the closure passed to the write() function gives read-write access to the various sub-fields within the register. However, the provided documentation link in the same section indicates that W gives write-only access to the register and cannot be used for reading.
