Data Fields
uint8_t	page
uint8_t	count
void(*)	read (void *ctx, uint8_t offset, uint8_t count, uint16_t *out)
	Reads count registers of the page from offset into out.
uint8_t(*)	write (void *ctx, uint8_t offset, uint8_t count, const uint16_t *in)
	Returns 0 to accept, or a link_nack_t to refuse with a reason.

Detailed Description

One page, as the IOmcu sees it.

read is not optional: a page nobody can read is a page nobody can check against what they wrote. write being NULL is what makes a page read-only, and asking to write one is answered rather than ignored.
