ONLY and is set by the chip and cleared by writing a ”1” to the bit or by

Bus RESET. Under normal operation the host should clear the PAV bit

after PPRIM is read.

PROVIDER PARAMETER provides additional information about the

reason for the receipt of certain primitives. The following table shows

PPRIM

PROVIDER PRIMITIVE is written by the MK50H25, in conjunction with

with setting the PAV bit, to inform the user of link control conditions.

Valid Provider Primitives are as follows:

Init Confirmation: Indicates MK50H25 Init Block reading has completed.

Watchdog Timer Expiry Indication: Indicates expiration of TCLK or RCLK

watchdog timer as determined by the value of PPARM. (PPARM=1indi-

cates TCLK, PPARM=2 indicates RCLK If PLOST is set it indicates

both RCLK and TCLK watchdog timer expiry). Issued only if enabled.

Error Indication: Indicates an Error condition has occurred during the

Information Transfer phase that requires instruction by the Host for re-

covery. See the PPARM table for specific error conditions. Appropriate

Host responses are Connect Response or Disconnect Request.

Remote Busy Indication: Indicates change in the Remote Busy status of

the MK50H25. See PPARM table for specific conditions. This primitive

is only generated if RBSY (bit 11 of IADR+16) is set = 1.

Connect Indication: Indicates attempt by the Primary station to establish

a logical link (SABM received). Appropriate user responses are Con-

nect Response or Disconnect Request.

Connect Confirmation: Indicates sucess of a previous Connect Request

by the user. A logical link is now established.

Reset Indication: If a logical link has been established, it indicates an

attempt by the Primary station to reset the current logical link (SABM

received). Appropriate user responses are Reset Response or Discon-

nect Request. In Transparent Mode or Disconnected Phase, it indi-

cates expiry of timer T1.

Reset Confirmation: Indicates sucess of a previous Reset Request by

the user. The current logical link has now been reset.

XID Indication: Indicates the receipt of an XID command. The data field
