 * Control byte (MSB first): 1 CP T2 T1 T0 RSA RSB OS

 * Charge pump CP = 1 (high) for TV, 0 preferred for FM
 * Test mode setting T2 = 0, T1 = 0 or 1 (MK3), T0 = 1
 * Freq step size RSA RSB = 0 0 (50 kHz, FM), 0 1 (31.25 kHz), 
 *                          1 0 (166.7 kHz),  1 1 (62.5 kHz)

 *
 * AGC time constant ATC = 0 (2 sec)
 * AGC top setting AL2 AL1 AL0 can take several values but the ones that 
 * matter are 1 0 0 (106 dBuV, PAL, NTSC, FM) and 1 0 1 (103, L/L').
 * Upon power-on reset this gets set to 112 dBuV so it must be set on init
