Data Fields
uint16_t	raw
	Raw 16-bit COININP word.
uint16_t	count
	Last good meter (status bits cleared).

Detailed Description

Parsed JVS coin slot state.

Updated from JVS COININP (0x21) during periodic polling. Use mie_read_coin_input() to copy the latest cached slots; that function does not issue a separate bus transaction.

Each slot is a 16-bit meter value in JVS wire order. Status flags MIE_JVS_COIN_STUFF and MIE_JVS_COIN_COUNTER_BREAK occupy bits 14..15 (MIE_JVS_COIN_BUSY). When either flag is set the driver keeps the previous count and sets mie_jvs_inputs_t::coin_fault for that frame.

On a normal reading, count is raw with status bits cleared (raw & ~MIE_JVS_COIN_BUSY). Coin inserts are detected as positive deltas against the previous count.
